Some shapes work better as text; some as video; some as visual lists. Forcing an idea into the wrong shape is the most common reason cross-platform repurposing fails. ### Idea shapes 1. **Single-claim ideas.** "Replies drive more growth than posts." One sentence; one assertion. Best as: tweets, single-post X / Bluesky / Threads. 2. **List-based ideas.** "5 mistakes that kill new accounts." A discrete number of points. Best as: carousels, threads, lists. 3. **Story-based ideas.** "Here's what happened when I shipped a launch." A narrative arc. Best as: threads, Reels with voiceover, longer X / LinkedIn posts. 4. **Process-based ideas.** "How to set up a Bolta workflow." Sequential steps. Best as: carousels, screen-recording Reels, thread tutorials. 5. **Visual ideas.** "Here's what my desk looks like." Inherently visual. Best as: Reels, single Instagram images, Stories. 6. **Comparison ideas.** "X vs Y." Two-column structure. Best as: carousels (slide-by-slide), threads (point/counter-point), single image with overlay. Most ideas fit one or two shapes well. Forcing them into a third shape often produces weak content. ### When to multi-format an idea Strong ideas often work in 3-4 formats: 1. Original tweet (short, single-claim). 2. Thread expansion (story or list). 3. Carousel (visual list). 4. Reel (video version). Each format reaches a different audience and reinforces the idea. This is real repurposing. ### When to pick one format only Some ideas only fit one form: - A pure visual works as a single image; doesn't need to be a thread. - A complex framework with 8 components is exhausting as a thread; better as a carousel. - A 30-second moment is a Reel; not a tweet. Don't force-fit. Pick the strongest format for the idea. ## Lesson 2: Best Format Per Platform Each platform has formats it rewards. ### X / Twitter **Best:** single posts, threads, native video. **Worst:** carousels (don't exist natively), long-form essays. ### Bluesky **Best:** single posts, short threads (3-5 posts), boosted single ideas. **Worst:** very long threads, video-first content. ### Threads **Best:** single posts (200-500 chars), carousels (visual + text), short Reels. **Worst:** long threads (Threads's reply chain isn't great). ### Instagram **Best:** Reels, carousels, Stories (for funnel, not discovery). **Worst:** text-only single image posts. ### Facebook **Best:** Reels, single posts (200-500 chars), Group posts, Messenger conversations. **Worst:** carousels (lower discoverability than IG), long threads. ### LinkedIn **Best:** medium-length text posts (200-400 words), carousels (PDF format), native video. **Worst:** very short tweets, Reels-style content. ### Mastodon **Best:** medium-length text posts (200-500 chars), threads of 2-4 posts, hashtagged niche content. **Worst:** carousels (no native), Reels (don't federate). ### The cross-platform implication If an idea has no good fit on a platform, skip that platform for that idea. Don't force it. A purely-visual idea probably skips X and Mastodon. A pure-text contrarian take skips Instagram. That's fine. Not every idea needs to land everywhere. ## Lesson 3: The Format Decision Tree A simple flow to decide which formats to use for any given idea: ### Step 1 — Identify the idea shape Single-claim? List? Story? Process? Visual? Comparison? ### Step 2 — Pick primary format Pick the format that fits the idea best. This is your "anchor" version. - Single-claim → primary tweet or post. - List → primary thread or carousel. - Story → primary thread or Reel. - Process → primary carousel or Reel. - Visual → primary Reel or single image. - Comparison → primary carousel or thread. ### Step 3 — Identify reasonable adaptations Look at your platform portfolio. Which platforms can host the primary format with light adaptation? For example: - A primary tweet works as: tweet on X, post on Bluesky, post on Threads, short LinkedIn post, Mastodon post (with hashtags). - A primary thread works as: thread on X, thread on Bluesky, carousel on Threads/Instagram, longer LinkedIn post. - A primary Reel works as: Instagram Reel, Facebook Reel, native X video, Threads video. ### Step 4 — Skip platforms where the format doesn't fit If a primary thread doesn't translate to Mastodon (where threads aren't great), skip Mastodon for this idea. Don't force. ### Step 5 — Adapt voice register per platform Earlier lesson covered this. Same voice; different register per platform. ### Step 6 — Schedule with offsets Don't post all versions at the same minute. Stagger across hours or days. Different audiences see at different times; the staggered approach reads as deliberate. ### A worked example **Idea:** "Most founders confuse autonomy with quality." **Primary format:** thread (the idea benefits from setup, claim, and elaboration). **Adaptations:** - **X:** 5-tweet thread. - **Bluesky:** 3-post short thread (Bluesky rewards punchier). - **Threads:** 3-slide carousel + Reel teaser. - **LinkedIn:** 250-word essay-style post. - **Mastodon:** single 500-char post with hashtag. **Skip:** - **Instagram (Reels)** — the idea is talky; doesn't make a great visual. - **Facebook** — depending on audience, might skip. That's 5 platform versions of one idea, each native to its platform. Repurposing done right. ### Common myths 1. *"Every idea should be on every platform."* It shouldn't. Force-fit reads as forced. 2. *"The same format works everywhere."* It doesn't. Each platform's natives differ. 3. *"Carousels work everywhere."* They don't — most platforms don't have great carousel support. ### Action Steps 1. Take one idea you'd like to share. Run it through the decision tree. 2. Identify which 4-5 platforms genuinely fit. Skip the rest. 3. Draft each version. Notice which versions feel forced and which feel natural — that tells you the platform wasn't actually the right fit. Format mapping is a craft skill. Practice it deliberately.
