Not that well. In order to have a My Little Pony: Friendship is Magic community on Dreamwidth, I had to create it myself (in 2011). Since the get go, although I've been able to attract over a hundred (mostly inactive) subscribers, I've done nearly all the posting. I can't remember the last time anyone else has posted to the community. A few people comment on the posts, but that's all. It's like it's my personal blog or something and I don't have the energy or interest to cover the entirety of the creative endeavor and news that is generated by all things MLP:FiM. So I don't have a community, I have a hermit's shrine.
