KMWorld publishes a list of Trend-Setting Products each year, and I’d like to mention the award winners that are integrated to some degree with SharePoint. 

The full list is here:Trendsetting-2009

I started listed the companies that had integrations with SharePoint, but the list became too long.  (Oh, Snap!)  So, I’ll just point you again to the great list of Trend-Setting products for 2009 from KMWorld.
