getMarked provides instant one click viral crowd funding for everybody in the world at web scale.Awesome stuff.

Thinking it over a bit if I were to start up a web project that involved getMarked it would actually make more sense to use Wordpress considering it's the most widely used CMS. And since it's likely going to be high on the list of things that we would want to integrate getMarked with it just seems to be a better idea to start with that instead of trying to get fancy using a newer CMS.
Still have a lot of thinking to do on exactly what I want it to be. But I'll probably just start out with some articles or something a long those lines and go from there. Eventually though I would definitely like some sort of discussion forum type thing that uses Marks. I think that can be a great application of getMarked.
Yes Este, I was remarking on WP with my blinkers on as a CMS but of course, it everywhere and therefore an absolutely ideal first candidate CMS for getMarked integration...
