Over the past 3 years I have been using (...shamefully) SharePoint 2007, DNN and Tridion to develop web portals. I am however looking to move off SharePoint and Tridion (lack of control over urls, markup and tdd) and am looking for alternatives.
Which of these would your vote go to and why? Could you share any experiences you have with these?
Although Orchard and Sitefinity seem easily extensible, I am worried about community support.
Thanks
Orchard is being developed by the Microsoft team and being pushed by Scrott Guthrie, Scott Hanselman and others, so support should be no problem at this point. Orchard is being build on top of the new features of ASP.Net MVC 3 and so is state of the art. My vote would be on Orchard.
