Izea the people behind Pay Per Post and now Social Spark is going to have a Izea Fest in September 11-13 in Orlando USA. They will have some very nice guest speaker like Jeremy Shoemaker from shoemoney.com and Merlin Mann from 43folders.com
The cost starting from 50 US and if you want to sponsor the even you can do that for 2850 US.
You will learn thing like “What advertisers really want” and “How to drive traffic to your blog”
I am sure if you live in the USA and make a living on the internet I am sure this is money well spent.
