It appears that NewsGator (news, site) is on some kind of roll. The provider of social solutions for the enterprise has gotten a thumbs-up from several hands this year, including Inc. magazine, which named them one of the 500 fastest-growing companies in the country.

Social Sites, the cream of NewsGator's crop, was designed to provide enterprise 2.0 capabilities to Microsoft SharePoint. In addition to collaboration tools, colleague tracking and content mash-up capabilities, Social Sites also offers ad hoc communities, profiles and a graphical display of a person's social network (strongest colleague connections, recommended connections, suggestions for best ways to connect).

Most recently, the company also tacked on Socialpedia, an internal website that leverages SharePoint's wiki capabilities, and Knowledge Explorer, a graphical expertise map based on Silverlight which shows all the people knowledgeable on a certain topic.

As for their recognition from Inc., the team says: "While not a complete surprise, it’s certainly an honor, and an affirmation of our rapid growth and success in enterprise social computing."

The recognition is in a pot with several other NewsGator sweet spots from 2009, including the Microsoft 2009 Best Social Computing Solution, KMWorld 2009 Companies That Matter, 2009 Colorado Companies to Watch, and the Upshot50 2009 Marketing Technology Leader. Inc.'s complete list, which features some other familiar faces, can be found here.

Continued the team at NewsGator: "We’re grateful. Honors are cool. But bottom-line results for our customers are what inspire us to keep getting better." Watch them do just that here.
