Other than someone who 'leaps to mind', what other criteria are you looking for in a reviewer?
Are active developers in a category welcomed to review their own category? It would seem logical that they would know their area best, but does that have too much potential for bias?
Does the review merely have to be well written and informative to be considered?
Have you considered some sort of "Freshmeat's choice" labels for apps that are 'best of class'? Or is that a headache you want to avoid altogether.
BTW: the popularity and ratings are excellent additions. I hope the reviews take off as well. I've always wanted a quick way to find the 2 or 3 'best of class' apps.
Another "me too"
I've only been running my project for 4 months and everything said here has rung true for me as well. Luke has expressed exactly what I've been going through. I hope this encourages others while educating prospective developers on some of the challenges in store for them.
All of it is worth it when you start getting those "Thank you so much for your product..." emails.
