Pretty cool, but it's been possible to tip users bitcoins on Reddit for a while now. (http://www.reddit.com/r/bitcointip). Although this has the advantage of being fee less, since it can stay within Coinbase and avoid the blockchain.

Thanks for pointing this out. We wanted to do one that was (1) easier to understand for users new to bitcoin and (2) used the free micro-transactions feature on Coinbase that you mentioned. Number 1 in particular I think is really important, but it is still a work in progress, so if you have any ideas let us know!

...And (3) force people to either create a Coinbase account or lose their money. (The post wasn't very clear, but as I understand it the receiver will get a PM linking them to Coinbase where they will need to sign up to receive their money).

I don't want to just sound cynical, so I'll try to provide a solution. Perhaps there should be an option to reply to the BitTip PM with a regular Bitcoin address where all future payments will be sent.

The micro-transactions are off-blockchain (an in-network transaction between Coinbase accounts) - unfortunately that's the only way to get them for free without any miner fees (many are very small amounts). However, if you accumulate enough tips (at least 0.01 BTC) in your Coinbase account you can then send them out of Coinbase to any other bitcoin wallet and we'll even pay the fee for you. We don't want to have any lock-in there.

It would be nice to receive your tips at an external address like you mentioned, but the miner fees could be greater than the amount you receive with such small amounts.

The existing bitcointip on reddit is offensive on many levels, the main problem being all of the bitcoin enthusiasts that upvote someone's tip, and the verification even though neither contribute anything to the comment thread, and pushes actual conversation about whatever the topic is down in the thread which kills the reading experience for the user at the sake of promoting bitcoin.
