PickyDomains is expected to hit six figures this year
The current incarnation of PickyDomains' service is at id 722 (http://pickydomains.com/node/722), and started at 15 (http://pickydomains.com/node/15). Assuming continuous ids and no refunds, 707 domains have been processed on the site since April 2007, yielding $17K in revenue for the site and $17K in payouts. It's possible there are other revenue streams -- via domain registration affiliate programs for one -- but six figures is unreasonable unless I'm missing something.
b) How many of these businesses will be around 10 years? I'll put the over/under at 5.
