"... nice job. I'm surprised however that people are willing to pay for this type of service. ..."

It appears to be a toy product but if you consider:

* As a twitter subscriber, reading multiple posts are a pain to read. This is a real problem for users and their subscribers.

* Twitter has a lot of potential users/businesses looking for ways to automate etiquette.

* Twitter has a lot of users

The real problem for any developer here if I get a product with a lot of users, will Twitter just roll out the same product or will they pay enough?
