There are some nice ideas going on here.
Let me pitch in mine too.
1. A web wallet.Credit with free 100/1000 tips when someone joins, which can be raised via community funding.
2. A template generator for a template, which displays the tips logo, a qr code and a catchy caption.
Use case.
As a user, I register at this website, which sets up my own personal tips account and give me the html script for a tips template.
I embed this template in my blog, and everytime some one likes my blog post, experienced users can donate via the QR code and for novices,
they can click on the url for web wallet, describe as 1 above, create an account and donate tip from there.
If we can get enough bloggers/website owners brought into this idea, we can reach to a lot of new people, if we can make the template design catchworthy.
Eventually in the longer term, when tips become main stream, we could replace the thumbsup/like logo in websites with tips logo.
