I'm liking it so far - bit of a learning curve but not too bad!

I do have a bone to pick with users - there are a lot of niche communities that have zero posts. If you start a community, try to add something to it! I'm not sure if people are trying to "claim" rights to as many communities as possible - i surely hope not - but if you're interested in a subject and want to start a community, surely you have something to say! It takes two hands to clap - if you don't start saying something, then whoever comes to your community is gonna move on.
