My Shared Items from Google Reader
Google Reader lets you share posts from the feeds you read. Right now I have a tremendously long commute in a carpool and I started using Google Gears' offline reading for my feeds. It works quite well -- until the car starts winding around a narrow mountain road and I feel like I'm going to throw up. But for a while, it does allow me some time to check out my feeds.
At the top of my blog there's a link called "shared from google reader."
The shared items shows all the posts I've come across that I think are worth reading (for my interests anyway).
The shared items page even comes with a feed. This shared feature is one of the neatest and easiest ways to share good posts without creating a link blog.
If you have a shared feed with Google too, let me know. Also, if you've never used Google Gears (which allows you to read your feeds offline), check out this tutorial from Lifehacker.
