Hello Lady, believe me nobody has less tech knowledge than I and I have been in the online marketing for 6 years. I find the benefits of these show to be in building relationships with other webmasters and the affiliate managers.
I think if you plan to seriously go after this market then I would definately attend the show especially if it is in your home town. I am flying nearly 3,000 miles to attend (but i must admit, I love Las Vegas).
