I didn't really know that anything like the RSS thing existed. I guess in a small way I had experienced something like that anyways when facebook sends e-mails to me whenever anyone does anything to my profile. I think that it's a good way to stay updated on a large number of things.
Google documents in a great way of doing things! I think it makes life a whole lot simpler. You can save things just as easily and this way they're anywhere you are and you dn't have to save and e-mail them to yourself. Great invention google, good job!
Web 2.0 is a newer way to work with the internet. It takes what people want and makes it easier and better for them.
