I think it’s the way the algorithm works on Lemmy. I was on Lemmy.ml for a bit initially (until I found the tankies…) and yeah the front page didn’t change much at all even federating with other Lemmys. But I don’t think it was from lack of content. When I switched to Kbin the posts would cycle much more frequently and since Kbin enabled federation it’s really felt like there’s enough here to replace my Reddit scrolling addiction.
The one about not saying “I think maybe” is one I actively try to do. Assertiveness is something that doesn’t come naturally to me but I’ve been in too many situations where my lack of assertiveness comes across as uncertainty and introduces confusion into discussions where actually I do know what I’m talking about.
