Would you like to collaborate with other bloggers? Grou.ps is a service that promises to deliver all of the collaboration tools you may need, in one place. You can run of the tools just by using a single login, instead of going to different websites to use a specific collaboration tool. Grou.ps supports wikis, photos, links, blogs, calendars, chat, forums, maps, profiles, and subgroups. I have to admit that it is a quite long list. They also allow modules by which users can pull in their data from other third party services such as Flickr, Digg, or even blogs. Let us hope that there will be more sites like this coming out in the future, as they can be quite useful in many circumstances.
