I really liked this well organized site. I like the Community of Moms...how fun to search for issues I am having with my own kids. I really liked the organization of the site. I love Google Maps and Google Earth. Both sites are fun and I use them in my clss all of the time.
I used Craiglist to buy and sell items a lot. Most recently I rented my house from an advertisement on Craiglist. The couple moved from Canada to Houston! They even pay using paypal! I love it!
I really am going to start using Google Docs more! I love it! I think it is very handy for me!
