I am making more money from .pro than any other extension. I have sold 15 .pros in the last 18 months for an average sale price of $3,000. To put that into context, not one of the domains on Microguy's for sale page is priced at $3,000 or above;
That's the equivalent of 60% of my investment in the extension for 5% of my .pro portfolio. I sold Insure.pro for $4,700 yesterday on Sedo and picked it up for $275 at Snapnames in April 2010. That's a 17 fold return on my investment in 10 months.
The growth stats for .pro are fantastic. Here are the last 9 monthly growth rates for total .pros registered.

People who knock .pro don't understand branding. For example, I registered Kiosk.pro in October 2007 long before the iPad was launched or this app;

There is no particular value in Kiosk.pro to a reseller on NP but to a company, it's short, memorable, and catchy. The .pro adds credibility and trust. Kiosk is a commercial word, people sell from kiosks and there are only going to be more kiosks around in the next 5-10 years retailers become more automated.
Domaining is a volume game, you also need to do something before other people do it to make money. I feel sorry for people like Microguy, they waste their time posting Zero on newbie appraisal threads because they are also rans who follow the crowd years behind the action and it's the only way they can get any attention. My advice is to do something different in domaining, whatever it is, make some money, then you won't feel the need to be mean minded to everybody starting out.
