Screwy Signature Linkage

Sorry, I tried searching this before asking, but all the suggestions were what I think I have already tried.

When I click on the links in my signature, they take me not to my blog and twitter, but to a 404 not found absolute write page.

What am I missing here?
Thanks!

Big, fat, wet, kisses to you Medievalist! That did it! I guess I am so used to just typing www. over whatever starts with http:// that I didn't think of that.

FIXED!
