I'm rather fond of !dull_mens_club@lemmy.world . You need not be a man, and you post about the dull goings on of your personal life (e.g. "made a ham sandwich today," or "fixed my washing machine over the weekend")

Check these two

• !casualconversation@piefed.social
• !ask@piefed.social

They are PieFed communities but you can join them from Lemmy

!general@lemmy.world is General discussion

!politicaldiscussiin@lemmy.world is Political discussion

!chat@beehaw.org (not accessible from lemmy.world)

!chat@lemmy.one (inactive, server shut down)

!canada@lemmy.ca is a mix of news articles, discussion and anything Canadian that doesn't really fit well anywhere else.

some of these are "ask" communities which sometimes turn into discussions

• !ask@lemm.ee
• !asklemmy@lemmy.world
• !askmeanything@lemmy.ca
• !casualconversation@lemm.ee
• !casualuk@feddit.uk
• !Dullsters@dullsters.net
• !dull_mens_club@lemmy.world
• !forumlibre@jlai.lu
• !general@lemmy.world
• !nostupidquestions@lemmy.world
• !goodoffmychest@lemmy.world
• !preguntalealemmy@feddit.cl
• !rant@lemmy.sdf.org

!nostupidquestions@lemmy.world is also pretty good.

movies, entertainment, without getting potentially sanctioned or astroturfed like you on reddit for discussing the same things, especially people are so fixated on the actors that they would defend them even if became they became POS. TIL, and sometimes news.
