I sort of doubt this is, in fact, the biggest question for most people. Or even most people among those on Twitter, who are a small fraction of the total population. Or even those users of Twitter who have fallen within its reality distortion field and think that their follower count means anything, since the reality distortion field suggests that the count is important rather than the individual followers.

Your startup requires that X perform an operation which is expensive in terms of time, effort, and perceived risk (installing a plugin and then commenting) without receiving value so that Y can receive value. That is a virtually perfect recipe for not gaining traction.

Very nice design, though.
