Change... know when to hold 'em... when to fold 'em

My last post was about a piece of writing submitted to an online community that was rejected.  Further changes are happening in that community and I am questioning whether I will remain a part of it or let it go. 

My first thought is that if the people who run the community knew I was contemplating leaving they would probably say "Don't let the door hit you in the @$$ on the way out!"  Maybe I am wrong, but I am really not part of the "core" crowd in that community so I would likely not be a big loss.  Additionally, there is only so much fresh content one person can come up with, so not belonging to that community would give me one less place I need to wrack my brain for "what to write" ideas.

The flip side of this is that I feel more and more that the only way I am going to grow stronger as a writer is to belong to writing communities where I don't have to be on the hunt for good writing, I can just log in and there will be a plethora of writers whose prose I can read and maybe I can start to pick out what elements are getting comments and which writers seem to have a large, strong following.  Although, for the life of me, I cannot fathom why some bloggers have huge audiences and others have 2 or 3 (it seems) readers.  I've read some incredibly wonderful blogs that have very, very few comments... so maybe I just know what *I* like and not what appeals to the masses.

So, I am still pondering the correct course of action.  Any thoughts?
