seoagent ~ What a lot of words to say that you don't really know much about Traffic Kahuna. In fact it has been around for a while, but not for open membership. Hundreds of people, of whom I am one, have been using the core tools, which are much more than just a blog network, for the best part of a year now.
I have to say the blog tool is my favourite.

Taking just the blog tool: it is a very large and dispersed network of sites all owned by real people with a real interest in building and maintaining good quality sites, the system is based upon managing quality and is very effective.

Even if the tool package was designed to have a short life I know that my return on investment each month is very good indeed. I get results that I need and save a huge amount of time. I also get content for my sites and can, generally speaking, dominate search terms in which I am interested and nothing black hat, or that I would prefer to not be seen. If the system closed tomorrow I'd have profited hugely on each month's payment.

Does the system of tools suit everyone? Absolutely not but it does suit me and the hundreds of folk using the system. Having seen the tools over time I also know that any limit on numbers is NOT due to limitations in the use of the tools but it does enable the owners to manage support, training and development without falling foul of the issues of uncontrolled growth.

Rather than spouting off about something about which you obviously know nothing, take a look - get a credt card out and come kick the tyres. If you find that you are correct in your assumptions then get a refund. When you find you are wrong, you can still get a refund, although if you are wrong it'd be a mad thing to do. At least you will be able to write in a credible manner about something that you do now know.

Come on, take a look and write a fair report based upon knowledge, not upon fear and prejudice. You can do much better for yourself than you are displaying here.
