Re: last boost -- I think what #dreamwidth really lacks is a good mobile app; using the browser on a tiny screen is fine for reading but awkward for posting and commenting. If you miss #Livejournal and want to make Dreamwidth more feasible for people who do their socmed on smartphones these days, and you can code, maybe look into this?
If you still love #rss, Dreamwidth is also pretty good as an RSS aggregator.
@artsyhonker Definitely won't disagree on that score. I don't use mobile very much, tablet aside, but I can see where that's a big drawback.
