I use Wordpress, don't forget that Wordpress will charge you a monthly fee if you want to use your own domain. I get around it because my domain registrar lets me forward my domain to any address. So while I do have an inktronics.wordpress.com address, I just forward inktronicsblog.com to it. It also helps if I have to setup the blog on another service, I just change the address where my URL points to.
