I do the same with my tabbed browser. First pass through my flist I open a bunch of new windows. I scroll through the tabs and open new Post Comments windows. Finally I comment.

The only reasons I can keep up are: a) really new here, small friends list, and b) I've been totally goofing off at work and spending hours a day at work on lj. But work is strating to feel neglected, and I'll start cutting down on my lj soon.
