SAAS Marketing Help/Opinion

I need some help and opinion from folks who either run or use SAAS/Web based Marketing applications.

Being relatively new (circa one year) to Digital Marketing, I'm still learning the ropes and as such, I've created a service called Octopus (octopus.org) to help myself and marketers. The goal of the service, with the help of other Marketers/Developers, is to list Marketing apps as well as make them searchable and discover-able.

I'd appreciate your thoughts on the site and whether you think it would be useful.
