I have been following End User SharePoint blog by Mark Miller for a while now. Mark is building a great site which is focusing on SharePoint value for end-users. It is an unique place which provides valuable information on how you can utilize out-of-the-box functionalities. You can also participate in forums, workshops, subscribe to monthly newsletter and stuff.
Check it out here.
Mark and I also exchanged some ideas in last few months and you will be able to read about some of these on his blog. Stay tuned!
