Is My Font Readable?

I recently changed the template for this blog. When I start up IE and go the blog, the text is illegible because it is so small. For some reason, my IE starts with View->Text Size = Small. Once I set it to "Medium", the blog is readable. I've considered moving to a fixed font instead of a scalable font, but I don't know if anyone else is having this problem.

I would be very grateful for any comments you could leave. Also, if you know how to set the default text size in IE to "Medium" I would appreciate hearing about it.

Thanks in advance!
