I've asked myself the same question for the last 10 years. I started modelling earlier this year in the forlorn hope that I could make a few quid from selling content, but as an earlier poster, Vilters, i think ,stated, the quality of a lot of stuff in the MP has increased but the prices have been slashed to compete with the aparently huge increase in content creators. I have come to the conclusion that you can't make anything apart from a bit of pocket money out of Poser, and that will probably nowhere near recompense you for the amount of money you will spend on for example material and texture sets for your models, let alone the time taken to build them. As in most business situations where you need an agent to sell for you, you will finish up having to pay them 30-40% commission for the priviledge of them "marketing" or not, your product.  Hats off to the guys that keep the MP going, but personally I'm just happy building the models I need for my own personal use and using Poser as a hobbyists tool. At least it keeps me off the streets, that and the curfew lol :)
