BU baker here. By "announcements," do you mean how to do bread notables or how to add new material like Q posts or other stuff on top?
BU baker. If you have questions, I can also try to answer them (espec. if baker gets busy).
Every baker is different. I started gathering Notes at the top; goal is to get to the bottom (emerging notes). If it's my first bread, takes longer because I have to set up the kitchen. I post as soon as I get there, usually anywhere from 200 to 350. Then I post every 150 or so (unless there are a lot of new Notes OR I need feedback on notes). Some stuff is controversial & I want to post in order to give anons a chance to spot mistakes or tell me why something doesn't belong in Notes.
Example: there's currently a shill post showing a Simpsons cartoon where Notre Dame is burning. Guy who posted it had sauce, but it and the pic were fake. Another anon spotted it and gave the real sauce and real pic, which was different. So I dropped it out before baking.
Too early is better than too late. A little shitposting will take up any slack.
Time to compensate for hanging bread at 100%. (Any idea why is usually hangs?)
Hey, didn't I see this very late last night?
