For my first suggestion of what teachers should use to better their teaching lives I chose Google Reader. The teacher’s biggest adversary is time. I have found that Google Reader is the best way to cut down on wasted time going from site to site looking to see if they have updated information.
Google Reader is a must for teachers. With so many educational resources available online, it is a necessity to use Google Reader to save time. While there are other RSS readers available, I like Google Reader for its ease of use. From the Google Reader Help page
Google Reader is a tool for gathering, reading, and sharing all the interesting blogs and websites you read on the web.
Most webpages have an RSS feed. Anything with an RSS feed can be added to Google Reader. Teachers can find this useful to organize their news information, educational site updates, blogs, or even their classroom blogs. Later I will discuss using student blogs and Google Reader will be a way to check student work.
For teachers that are into using twitter. Twitter profiles include a rss feed, which Google Reader can pick up.
Here are a couple sites to help with your introduction to Google Reader.

Google Reader .Thanks for nice post.I added to my twitter.
Google Reader is one of my favorite technologies. It makes keeping up on blogs and education easy. I recently discovered some helpful Google Reader short cuts that I didn’t know about (v- lets you view the original for commenting, n- takes you to the next post, p-takes you to the previous post, ? reveals all the short cuts) so handy!
Kind of interesting how using a time-saver like Google Reader needs additional time saving hints.
ha ha you’re right. I feel good not to use shortcuts. I can’t memorize all of them.
