When I first heard about fandom-journalling projects, I was understandably slightly cynical, having seen JournalFen in action, which was pretty much a Harry Potter clique (and canon-thumping clique).
I believed that most projects would be started, a few would maybe get coded, fewer would enter a beta stage, and even fewer would actually open.
I saw Scribblit, which I have no idea what they're doing now, because Scribblit.com doesn't load and googling only gets the LJ community. I decided that it wasn't something for me, mainly because to me, it felt like the design was all over the place (and bright, bright green).
I looked at GJ, but decided that I didn't want it, which was lucky because they crashed when LJ started to migrate. Unfortunately, this made the LJers who tried GJ a bit fly-shy.
Anyway, I ended up on IJ, not even looking at DeadJournal (I think it was because I remembered something about it when it was new).
And now I hear about Dreamwidth, and I'm very, very sceptical.
You see, when the great LJ Migration took place, not only was LJ under different management, but they had also screwed fandom royally. Hence, a mass migration to GJ and IJ. Many choose GJ because they found the design more pleasant, but got a deaf staff and returned to LJ, and the few in IJ found that they were very lonely and returned to LJ or started crossposting.
In the end, there wasn't much difference in fandom.
That was directly
after LJ screwed up. Since then they have new management and, while fumbling, they haven't been the worst internet company in the news (see: Amazonfail).
Now DW wants fandom to migrate again. To them. With invite codes or by paying.
Remember LJ and the invite codes? Yeah.
Remember fandom run JF? Yeah.
DJ? Yeah.
Another GJ? Yeah.
Fandom remembers these services and will probably be cautious, if they consider moving at all.
DW might say that they are different than LJ-clone sites, that they have more fandom friendly stuff. But I don't see that much of a difference right now.
So I'll wait here at IJ, because it will probably take months or even years to see if DW will be the fandom hub it wants to be.
