well, you can STILL use tags and so you can still be visible on all those other tag feeds.. but they are way less accessable right now as there is no list of them anymore!

so for choosing communities.. well , this is gonna be fun! i think many people, including me, will cross-post some posts into our communities ourselves,, which is nice for the author.. and can spread things around a bit.. but otherwise the only way is double posting! !(perish the thought!)
