ChangeTip - Send BTC tips through comments, @mentions, etc...

Neat idea, reminds me of Starbucks' Tweet a Coffee program (https://www.starbucks.com/tweet-... - h/t @MattGartland for sending me a free cup o joe!). Perhaps we should add this to Product Hunt. :)

This was huge last night during the Bitcoin Bowl + they just raised a huge round.

Super fun to use in Slack and on Twitter https://changecoin.zendesk.com/h...

Flattr tried this some time ago... I think it's a tough-nut to crack (as evidenced by the number of attempts: http://gigaom.com/2011/05/11/why... ) - but that doesn't mean it's impossible. BTC could use a little liquidity too - best of luck to the Change Tip team.

It's cool they're using bitcoins for this. I think such systems could really make the obfuscated idea of bitcoins easier to understand and, therefore, more widely used. Nice hunt!
