UpTweet indeed looks like a better approach than Witcoin, with the distributed pay vs. per-post tipping. Tipping is a time-honoured tradition even by internet standards, but it depends on too many variables, such as people who would otherwise be happy to tip a post but happen to not have the BTC handy, don't have time to do the spend or upload to a Witcoin wallet etc.

Thanks for the thoughtful post Frank.
Give us some time, we will have Tweet tipping soon
...
Right now our biggest priority is the mobile application.
In the meantime I agree with you, we have a very innovative (dare, I say) radical platform, that feeds good posts, and shuns bad ones automatically (or subconsciously if you will).
We are excited and we hope you are to!
Kind Regards
