I was just about getting used to having a small selection of cms's to use, although not perfect, they could do the job. WP for simple blogging and more developed sites, tumblr for quick easy to setup sites, drupalgardens for microsites.
I then stumble across CrowdFusion.com on http://www.crowdfusion.com/news/2010/03/03/crowd-fusion-nytech-meetup-presentation/
A good site using this as an example is obsessable.com. Another good site is TheDaily.com which is very impressive.
So, my proposal is with wp3.1, can it step up to the mark of these more flexible structures/features and create site that are not just easy to setup, but can also be as flexible enough to bend in almost any direction possible?
The comparison option on Obsessable is WOW, along with many other features. this aint a plug for SF, but just merely a request for wpmudev top show how flexible they can make wp become with 3.1 and beyond.
