Thank you! Yes, I noticed the similarity too... complementing of eachother in a way.
It seems TinyPic has put it's plague of blur on your signature though (still don't know why it does that, I usually just cave in and use Photobucket); it's just this weird random issue that happens on any image where it degrades the quality from what it was uploaded at. Surprised they haven't bothered to fix that yet...
PS- I
love the David signature. It seems we're fans of frantic radio chatter.
