Maybe we should change the "tip" button to something like a "like". It's actually a bit similar to how a Facebook like button works. Here's what happens when you "tip" someone. 1. You send them some micropayment 2. The micropayment history is recorded and displayed on the post as a record 3. This contributes to the total economy of the post, and it gets bumped up inside the "active" tab. 4. Tipping also acts as a way to "watch" a thread evolve. By tipping a post even 1 cent, you will get notified whenever there's a new comment added to the thread. You can also get notified by commenting to the thread, but if you just want to watch the thread develop, this is a great way. Any thoughts?
