Bloglines has a little button that changes the sort from "newest first" to "oldest first," and I can leave part way through reading the messages and come back later and take up where I left off. With LJ I have to try and run through everything in a sitting, or else there will be messages I never see. It's really wretched, and changes this from being something somewhat enjoyable to being an onerous chore that must be completed NOW or never.

Reading from the bottom of the screen wouldn't solve this. I've tried going back through some pages, but finding my place that way is also inconvenient and time consuming.
