I started on blogging, and got an lj sometime this year, then moved over completely quite recently - er. I suppose it was a combination of reasons.

My lj was supposed to be a ficlog (because they have nifty things like cut tags, and I didn't need to be schizoid about layouts), with my blog for everything else. But then it seemed that I never had anything interesting to /blog/ about, and fell out of the habit of social blogging - so my blog got neglected. And I found all sorts of fun people, fandom-wise, on lj, so that was that.

I miss the layouts, personally (can't figure out those damn overrides, so I give up), but yes, you /do/ fell pressured to update with a blog that isn't quite as bad with an lj (not to mention, lj is /evilly/ easy to use...)
