Oh absolutely, DW is my primary journaling home now - I post here & interact here and plan on turning off commenting at LJ once we're out of open beta - I just have a very laizzes-faire style of comm moderation that I'm not sure will work with larger comms (I hope they flourish unto the point where this becomes an issue!).

Snagging usernames just to have them/keep others from them isn't cool (although in specific instances I can see how it might be acceptable for very well-known comms like pornish_pixies? even though I don't like it.).
