anatsunohas written a couple of posts asking for and listing Inception fandom resources on DreamWidth for people who have recently moved:
inception in dth and
inception on dreamwidth, 2.
First off,
inception is a relatively inactive comm that accepts all kinds of fanwork: fic, art, graphics, podfic, meta, recs. Let's make it active! I don't think the fandom is too big to have one unfiltered community (they have character and pairing tags anyway) and then branch off into more specific ones. I just issued a challenge on Twitter for everyone in the fandom who uses DreamWidth to post their most recent work to
inception. If you don't normally think of yourself as a creator, how about posting a rec list of fic, podfic, or art?
If you're interested in modding something, then head over to one of
anatsuno's posts and maybe find someone else to partner with you.
A lot of people who were formerly only on LJ have created or started using DW accounts in response to the latest comment kerfuffle. Remember that DW can be joined free without an invite code until the end of the year, and it supports automatic cross-posting to LJ if you want to maintain a presence in both places.
