Now that LiveJournal has been bought by Six Apart I'm hoping for some big changes to make the experience better and more attractive to new users. One of the most off-putting features of LJ is its lack of good design. The 6A team should find somebody to create better templates that are still unique to LJ but not fugly. LJ should continue to be community based, but I wouldn't mind if some elements of blogging were implemented like a linkbar, site statistics, viewing posts for an entire month, and categories. I doubt these additions would break the communties down at all. These are just a few suggestions off the top of my head, but for now LJ is still the same as before it was sold.
