I've been reporting alot on the Moguling phenomenon and yes..I'm very biased so let me get that out there.  Moguling.com has a tool that allows anyone that has a passion for the Internet and talking (Hey that's me), can potentially make a fortune with this.  Try one of the paid services ($99 a month), and I want to hear from you guys that use it.  You can place ads on these blogs in just days and write blog posts about your favorite things.  The iReporter tool does the rest!  You can cancel per the agreement after only 30 days, so not much to lose and lots to gain!  Click the yellow banner on this page!  If you are too cheap to spend $100 for perhaps the greatest internet marketing tool on the Internet, there is a free option but you really can't leverage the tool in terms of maximizing the profit potential.  Oh yea, the tool has built in SEO too!
