I have freshened things up around here and switched over to the iNova theme for WordPress. My old K2 theme has not seen a lot of development lately and I like the clean layout of iNova.
I also upgraded to WordPress 2.7 and love it! They have made some great improvements to the usability but the best feature by far is the auto-update functionality! I was using TypePad for some corporate blogs because updating WordPress was always a pain. Now that updates can happen in the background I highly recommend WordPress for all your blogging needs!
