It's the whole shebang, too: journal entries, comments, tags, filters, everything except my ridiculous gallery of icons (DW maxes out at 15, which really is plenty; LJ allows me 202, and I have 82. Time to pick and choose!)
LJ-specific templates like the Writer's Block questions didn't make it through; I don't know if polls did, either, since I don't use them enough to pick a poll-entry out without slogging through pages and pages of archives.
I don't know if I'm going to shift my primary posting habits over there, but now that I don't have to abandon eight years of archives, that's become feasible.
Of course, DreamWidth makes it much easier to cross-post, so it does make sense to make my posts from hereDW rather than over therelj.
