Online birthday rewards?

Tweet

Being my birthday I checked my E-mail for first time in a while and was not surprised to find some birthday wishes from sites I'm signed up on. But only expected "online greeting cards" really. Most were beyond lame though. But still nice to see some sites take time to do some extra stuff. One site though did send me an E-mail informing me I was given 50credits on their site (approx 55cents worth). Given the fact I recently cashed out $5 plus a laser pointer from their site I was surprised to be given more from them of value (at least value considering online earnings site). Wondering if anyone else was aware of some decent online birthday rewards?
