I'm glad you're staying here. LJ recently has been annoying me for something which is almost opposite your friend's reason -- there have been too many comments-locked posts. And posts with little real content (the 'twitter' things) which seem to be just "I'm here" and so nothing to really comment on. Posts like most of yours, which make me think and think /why/ I agree or disagree with the poster, seem to be on the decline (I can hope it's temporary).

And that's another reason I get frustrated with LJ. It's very difficult to get a real thread going which runs over several days, because it isn't (as far as I can tell) possible for anyone apart from the owner of a post to get updated when other people add comments (apart from the limited case when the comment is directly to the commenter). This means that when the original post scrolls off the end of everyone's flist the thread is effectively dead, and for most people I know this happens within a day or so.

I joined LJ in order to see friends' posts, and to comment. Without comments LJ is just a journal of not much interest to anyone apart from the author, or at least it is as far as authors are concerned because they wouldn't get any feedback.
