Blog And Search Tool With Internal Focus
The Nextaris Beta could be an interesting alternative for organizations when it comes to knowledge sharing and blogging.
Search Engine Guide describes Nextaris as "...an initial effort to integrate the various tools we all use in online research. Like other online web research managers, [it] lets you create folders to save cached copies of web pages, and search the content you've saved. There are also tools that allow you to easily publish the content you've found, to a web site or a blog."
I haven't checked it out in detail myself yet, but it seems to integrate many of the functions I would like in an internal blog platform. That is, one solution for external sources and news alerts, document management and organization, blog/web publishing, and messaging on a private network. I think I will give it a try.
