Now that the Facebook Platform has officially taken off there is a brand new market forming for web developers.

A quick look around and you’ll find lots of people looking to hire you to develop Facebook apps that will help feed the biggest spamming opportunity the web has seen since the advent of MySpace bulletins. These people aren’t offering decent rates, probably want offshore workers and should be avoided.

There is, however, some interesting movement being made in regards to selling Facebook Applications after they get a fan base. I first noticed this the other day when browsing Web Auctions Daily. There’s no clear model for monetizing these things so their value appears to be based on the size of their user base. Larger companies are beginning to scoop up applications made by independent developers that have high user numbers.

For a web developer between projects, or looking for a change of pace, making a Facebook Application might be worth looking into especially if you can get into a new niche early enough to attract a large number of users.
