Gonna be honest with the direction and quality of the average tweet on the site you'd have to pay me to read more tweets. Not sure how big the target demographic is for having people with profile pictures of Erwin Rommel and/or anime girls give you their take on current world affairs. I don't think you can run a pay for premium content model and 4chan at the same time.

I think a large fraction of the active userbase will be happy to pay, eventually. The catch is that the userbase will be so small by then it won't be enough to pay the bills.

It might yet survive as a personal PR machine, though.

The product is really more "pay to self-promote".
