I've been on livejournal for about eight years, and I usually check LJ every day. I don't skip over any posts, but I'm not very good at commenting.
When I write it tends to be contemplative, meandering, and really long. I don't write prettily or cryptically; it spills out in a rush. Sometimes I put up pictures.
My entries are all friends-only, and sometimes I go through and private most everything. I'm a very open person if asked, though.
