Class 76 taught you to meet someone at the exact moment they search. Social distribution works the opposite way around: people are already scrolling, watching, or arguing somewhere, and your work has to earn a pause inside behavior that already exists. You do not bring the audience to your format. You bring the idea to their place, in a shape that place already rewards.

Six platforms, six dominant behaviors

Every platform can technically host any format. What matters is what people come there to do. Match that, or your post feels like a stranger reading a speech at a dinner party.

• YouTube — searchable depth. People arrive to learn something properly, follow a creator over time, or solve a problem with a full explanation. Long videos, Shorts as entry points, comments that ask follow-ups, and a library that keeps working for years. Best when your idea needs demonstration, proof, and chapters.
• TikTok — entertainment and discovery. People arrive to be surprised in the first two seconds. The feed decides, not the follower list. Sound-on vertical video, fast cuts, pattern + payoff. Best when your idea can be shown in motion in under a minute.
• Instagram — visual relationship. People follow people, shops, and looks they want to keep seeing. Reels for discovery, carousels for saved explainers, Stories for daily presence. Best when the idea is visual, personal, or place-based — before/after, process, face, shop, neighborhood.
• LinkedIn — professional context. People read as their working selves: what helps my job, team, or reputation? Text posts, documents, and short work demos travel; jokes and memes die faster here. Best when the idea carries a work takeaway with evidence.
• X — real-time conversation. People argue, annotate the news, and trade short takes as events unfold. Threads, quotes, screenshots, and fast replies. Best when your idea has a timely angle or a crisp claim worth debating.
• Reddit — topic community. People gather by subject, not by personality. Each subreddit has written and unwritten rules, hated formats, and a memory for self-promotion. Best when you can answer a genuine recurring question better than the existing threads do.

Think of the local tailoring shop from earlier classes. A 12-minute YouTube video on "how a same-week hem actually works" fits searchers planning ahead. A 20-second TikTok of a torn dress rescued before Saturday fits scrollers who did not know they cared. An Instagram carousel of three recent rescues fits followers who like the shop. A LinkedIn post fits nobody — unless the owner teaches "how small shops schedule rush work," which is a work idea, not a hem. Same business, different behavior, different asset.

Native means format plus expectation

"Make it native" does not mean copy slang, dances, or meme fonts. It means respecting two things at once:

1. Format: the shape the platform plays well. Vertical 9:16 with captions on TikTok/Reels/Shorts. A readable carousel or 90-second demo on Instagram. A title plus opening 30 seconds that survive on YouTube. A self-contained post under 200 words plus one image on LinkedIn. A question or answer that reads well as plain text on X and Reddit.

2. Expectation: what the audience considers a fair exchange. TikTok expects a payoff fast and tolerates rough edges. YouTube expects the title's promise to be kept in full. LinkedIn expects a work reason to care. Reddit expects that you have read the room, answered the question, and are not smuggling an ad. Violate expectation and good production makes it worse — a polished ad on Reddit reads as a better-dressed intrusion.

A useful test: show your muted draft to someone who uses the platform daily. Ask "does this belong here?" If they say "it looks like a YouTube video squeezed into TikTok," you have a format or expectation mismatch, not a quality problem.

One idea, five ways

Take one researched idea — Research Desk turns a 100-page filing into a source-linked brief without inventing quotes — and watch it change shape while the claim stays fixed:

• YouTube: "I turned a real 10-K into a citable brief in 22 minutes" — screen recording, chapters, source links below, sample brief download.
• TikTok: vertical screen capture, first frame: "This filing quote is fake. Here is how I check." Three swipes, one check per swipe, payoff at second 25.
• Instagram carousel: 8 slides — problem, three checks, two mistakes, sample brief page, "save this checklist."
• LinkedIn: "Three citation errors I keep seeing in analyst briefs, with one filing example" — short post, one annotated screenshot, template link.
• Reddit: a text answer in a research or investing subreddit to "how do you verify claims from filings?" — method, limits, link only where the rules allow and the answer already stands alone.

Same evidence, same promise, five different openings, lengths, crops, and destinations. Lesson 77.3 turns this instinct into a reuse system. For now, notice the discipline: the claim never changes to chase the platform. Only the packaging does.

Exercise: choose one primary platform

Create PRIMARY-PLATFORM-CHOICE.md. You are choosing where to win first, not where to exist. Include:

# PRIMARY-PLATFORM-CHOICE.md — [Project]

## Audience behavior
- Where do these people already spend time, and what are they doing there?

## Idea fit
- Which one idea deserves distribution first, and why does it fit this behavior?

## Format strength
- What shape will we make weekly? (example: 60-sec vertical demo + caption)

## Capacity (honest)
- Who makes it, how many hours per week, what equipment/editing exists?

## Destination + first action
- Where does a viewer go next, and what is the one action? (sample / booking / signup)

## Primary choice + reason
- We choose [platform] because [behavior + fit + capacity].

## Deliberately deferred
- Platform deferred: ___ → reason / revisit date
- Platform deferred: ___ → reason / revisit date
- Platform deferred: ___ → reason / revisit date

Worked mini-example — ByeBuy Classroom: audience of builders watches YouTube to learn workflows deeply. Idea: "from filing to brief." Format strength: screen demos with chapters. Capacity: one recording session weekly. Destination: course map page with template. Primary: YouTube; TikTok second as cut-downs later; Reddit only as answers where questions already exist; LinkedIn deferred until a work-angle series exists.

Finish line: a PRIMARY-PLATFORM-CHOICE.md naming one platform, one weekly shape, one destination, and three platforms deliberately deferred with reasons.

Verify quickly: read your deferred reasons aloud. If any says "we will post there when we have time," it is not a strategy — it is a leak. Either name the behavior it would serve or keep it deferred.

Common failure mode: posting the same horizontal video with the same caption to five platforms and calling it distribution. Each platform forgives beginners; none forgives irrelevance at scale.

Check your understanding

1. What is the dominant audience behavior on each of YouTube, TikTok, Instagram, LinkedIn, X, and Reddit? 2. What are the two halves of "native," and why is slang-imitation not enough? 3. Why does choosing one primary platform teach you faster than cross-posting everywhere?

You know where to show up. Lesson 77.2 teaches what to make once you are there — the hook, the useful middle, and the next step — including three hooks and a 30-second outline you can actually shoot.
