Startup Idea : A copy of Twitter, but better and profitable.

Looking for a team to build a 'copy' of Twitter but much better and should be profitable. Looking for co-founding developer(s) who can build this (starting from the basics of course). The problem with Twitter is that it does not know its user. The result is that it's not a commercial success and can't buy/create new services. It started like a hobby and remained a hobby for the founders, lacking a proper business model! We will do the basics: LISTEN TO OUR USERS, to their wishes. KNOW OUR USERS. And build a solid business model and money-machine. Any ideas are welcome.
