SharePointPedia is the successor of the "Recommended Reading" lists on the Microsoft SharePoint Products and Technologies Blog. Here's what the have to say about this new site :
SharePointPedia.com is a web site where people discover and share useful content about SharePoint and SharePoint related products and technologies. It’s a social computing application built on top of Microsoft Office SharePoint Server (MOSS) 2007. Anyone with a Windows Live ID may become a registered user and can then submit content recommendations or requests, leave comments, or just vouch for whatever they like.
Note that SharePointPedia is not a wiki. It’s a “pedia” in the sense of being a compendium of useful content, but rather than being limited by just wiki functionality, it leverages the much broader set of capabilities in SharePoint. SharePointPedia is also about community, where you can find and connect with others, who have similar interests as you or who have recommended content relevant to you. We hope that you will find SharePointPedia useful, and we would greatly appreciate your feedback to make it even better.
The Microsoft SharePointPedia Team
