I like StumbleUpon. You don’t even have to have the button. You can just go on Stumbleupon.com and set up an account. Then click the button and have fun!
It’s unfortunate, @Rowdy, that you’re almost assuredly a bot/spammage, because that has the potential to be really cool. But because you’re a bot/spammage, I am forced to not actually support that site. Sad, really.
Sorry, I didn’t realize there was a real person connected to it. You can’t blame me, exactly, considering that the first and only post from that account was a website that is not too well known…
