I like twitter- it's short and sweet. I was able to find tla and ala using hash marks. Searching for people that have twitter accounts is really straight forward and I was able to find my friend Cary at The Colony Library. She has a following :-)
My only problem was finding a username that has not been used. I ended up with 23laurie. Using the RSS feed I added twitter to my Google reader. This may help me to keep up with all the feeds at once.
