Seems the WSO2 crew has been blogging about WSO2 appearing on the "cool 5" companies in a recent Gartner report (paid subscribers only).  What intrigued them about the WSO2 Mashup Server was support for the hitherto paradoxical "lightweight but enterprise-oriented" services.

And here I am a couple of days late.  I guess for breaking news and the real skinny on "cool" you would do well to add the feeds of Paul, Sanjiva, Daniel, Glen, and Keith to your blogroll.
