I have to confess to not being a huge Windows Sidebar fan as it cluttered my desktop but this new Windows Live Sidebar gadget may change all that. With the release of the Wave 3 of Windows Live you get excellent aggregation of content from Flickr,Twitter and elsewhere and this gadget displays all of that goodness on your desktop with a refresh rate you can set.

Check it out on Windows Live Gallery and thanks to Dare for posting and Brandon for bringing to my attention.
