People do read on DW! I read everyone on my reading list and most of the personal journals on my network list, pretty much everyday! (Except... right now, because suddenly it's a LOT.) But. Commenting is a lot harder than reading. I tend to assume that for every comment, especially on posts that aren't written to encourage comment, there are at least 40 lurkers, so if there were no comments there must have been 39 lurkers. :D
