Nancy,
I'm not an about guide, but I have been through Prep.
I agree that the selection process is inconsistent.
However, people going through prep don't actually spend an "inordinate" amount of time being stressed out and miserable. It IS a harrowing process--one that many people are not used to and, first time out, aren't expecting, either. Those going through prep come here to gripe and vent to those who've been there (or to ask questions!)
GardenWallPubs, I don't think celebrating your victories here would be odd--in fact, it would be great to hear the success stories as well as the headaches!
But, Nancy, the entire Prep process is so fast-paced and intensive, writers in the midst of it don't have a lot of time to post the "good stuff" until it's all done. (And if you look through the thread, you'll see a lot of About.com success stories here!)
I don't think the About.com reps come here because they have their own channels for sharing information with preppers and (this is just a guess) I get the impression that they are quite overworked themselves. If they spent time surfing this forum and answering questions, reviews would probably be even more delayed! I suspect reps from other companies come to these forums to share information, but also searching for candidates. About.com is definitely not hurting for prospects!
In all, the Prep process is a harrowing few weeks--with no guarantee of payoff--but a decent income writing on a subject you (presumably) love if you get the gig. Like any other job, you just have to ask yourself, is it right for YOU.
