On Twitter, tweet storms - threads - have become a popular way to share and distribute ideas both with and beyond the character constraints (formerly 140, now 280).
Individual tweets are great as minimum viable writing output. They are tiny, so they take a short amount of time to compose and write. And you can get feedback from your followers or others interested in the topics you discuss.
Threads are a bit longer. Threads are a nice middle ground between a tweet and a blog post (or book chapter, for that matter). You can string a large amount of tweets together into a storm, if you really want to. (Best practices seem to keep tweet storms between 2-20 tweets - still short. Why? They clog your followers’ Twitter feed for a short amount of time.)
The size constraints and ease-of-publication that tweets and tweet storms allow make them incredibly useful tools for writers. However, they’re both public. You might not be ready to share your thoughts with a public audience. You can adapt the same format - tweets or threads, as smaller versions of a blog post - to other mediums, like text messages or chat messages on shared messaging app like Slack. You might find that a smaller audience - even an audience of one - is a better or safer way for you to start sharing your ideas with others. You could even write “tweets,” “threads,” and “blog posts” in a very private setting - to just yourself - as a document that only you have access to.
In any case, starting small and keeping it informal might take the pressure off writing and help you get started with the writing process.
Storms are just one more medium to keep in your writing toolbox. Different mediums are useful for different points in the writing process. Two key variables are length and openness. This diagram shows you some of the options you have available and how they relate:
