Hm, not really. I don't think I'd benefit from many of these improvements (being traditionally female, not blind, and neither a fanfic writer nor a community owner) and I'm actually quite content with LJ. I don't do much over here, so there are not really any problems.

Oh but MLA is a wonderful style, at least in my opinion. In German Studies, I always mix it with the styles that are recommended to us.
