One of the nextNYers pointed us in the direction of Stikipad for our website. At USV, we like the idea of a blog as a website, but nextNY isn't really a group that's going to be doing a lot of publishing, at least not as a group. We have some individual bloggers, but we needed a site where we could collaborate on ideas, and put our links to Flickr, Google Groups, etc. all in one place. It needed to be easy, but we also wanted it to be branded with our stuff.
Stikipad proved really easy to setup and the interface is simple and responsive. The best part is, with a pro account, they allow you to map a domain to it. So, our Stikipad hosted wiki is located at www.nextny.org.
Its early in the site's development and it doesn't have some of the apps that Jotspot does, but I'm sure they'll get there. I had a little e-mail exchange with Matt and he seems like he's on the right track.
In the meantime, check out our site!
