After a few requests, we’re not tentatively listing the #cafe category in the main page as well.
That category is open ended and not restricted to snaps. Conversations there resemble a bit the conversations we’d have during breaks while walking to that cafeteria around the block. Unfortunately we couldn’t choose the proper country for that cafeteria, so we decided to have those conversations online as well. 
If it becomes too awkward, we may take it off from the front page again. But looking at topics there, it feels like this may be fine and welcome.
