WordPress is killer blog software. It’s powerful, fast, well developed, etc. The catch is, you have to download the software and put it on your own site. If you don’t have you own site, you’re out of luck.
Enter WordPress.com. It’s the same theory as blogger.com, except it uses WordPress, which is killer. For those in the know, this is a full blown install, with all the perks. You can upload images to it etc.
I highly recommend moving to WordPress.com.
