One thing I suggest is to change the admin skin, because right now it doesn't look very pretty (in my opinion): too many different colors (for ex.: blue, green and purple/magenta on the same page — it just doesn't look solid), overuse of drop shadows, in some places there is too much white space which could be used more efficiently etc. To put it in a nutshell, work more on the looks of admin panel so that users could easily manage their blog. Well, it's just my advice.
