I just learned that Google has made available a share page from their Google Reader app. Whenever I read an article or something and feel it is valuable, I share it, and you can go an read that article.
I have had an application on the side of my blog for awhile, but Google now gives you your own page. It looks great.
If you want to check out some of things I have found useful enough to share, check it out here. Topics are VERY varied.
