One drawback to running a blog on your own is having to update. It really is the only major drawback, but the advantages of controlling all aspects of your own site is worth it in the end.
All that being said, the brains at WordPress have already upgraded the recently released version 2.3 to 2.3.1. You can read all about the fixes, and grab the update, here. It seems to be a fairly major update with over 20 bug fixes for those where at 2.3 already.
Don’t ever think you can just skip these incremental updates as there are bots out there that look for older installs to attack.
