Would 5% of twitter users be willing to pay?

Not for long. Web hosting is something people need, and once they find a provider they like they tend to stick.

Twitter is something no one needs, people would happily move along to a free competitor, and we're not talking about software or infrastructure that would be difficult to duplicate.

The tiny percentage who would pay would quickly change their minds when all their followers migrated elsewhere.
