I'm definitely not expecting to spark some mass exodus from FB but more users is necessary for scaling, conversion diversity, etc. A ton of reasons really, you is smart, you know. If current regular users could double the user base, I think it would go a long way in helping sort out a lot of issues by providing fresh feedback, data, surfacing new problems, whatever. I waited a long time to even try recruiting because I wanted to understand what I was using first. Then I waited longer because I much enjoy our weird little corner of the internet as it is. But growth appears to be flattening after the September push, so I figure it's time.
