For short form, just share links with a little bit of commentary. Makes a lot of difference and saves people time deciding whether to click the link.

For longer stuff, just start writing. Do so in a markdown editor, as you can preview in real time. And after 2/3 hours tell yourself you’re not going to post it. Then you can come back to it another day and build on it if necessary. I tend to rush stuff out, even after spending hours or days on it. A 2nd set of eyes before publishing isn’t the worst idea, if you want it to have real impact. I tend to skip that step and get too excited about posting what is 90% done.

Another tip I found is tell people here in the saloon what you’re going to write about and I promise people will check back and find out how it’s going. Because they genuinely have an interest in the same topics.
