i checked your blog. my first concern is that it's on someone else's website, effectively growing their asset rather than yours. yours grows a little, but it'd be better on your own site.
you can check out
Ueuo.com - Free Web Hosting Area for some free web hosting, they have a one click install of wordpress and their own dns for redirecting your url. that's who i use. technically it's still growing their asset but i don't have a little logo in the corner of my website. you can also pay $1 a month to have them totally remove the popups from your site. I'm considering this now.
