I've also got a Google personalized home page, which sounds LAME, I know it does, but basically I sign into my Google account and then I've got a bunch of features, some third-party (i.e. not Google-written) and some not. One one page, I can see if I've got new Gmail, I can view my Google Reader blog updates - sorting by most recent or by category and then most recent - I have the weather forecast for my area, I've got a little stopwatch widget (for when I take a break and play Candystand games), I've got a Google calendar (which I should use more than I do), I've got news feeds from the Boston Globe, the New York Times and NPR, I've got a wee Digg box, and some other stuff I don't really look at. It used to have a myspace widget but it was unreliable so the creator took it down. I can sign into my iGoogle page from anywhere with an internet connection and see my stuff (mostly I glance at my Gmail and the FeedReader.)
Anyway. I wasn't meaning to write about the google home page, I wanted to write about the RSS reader thing, because it is so super useful. I just got sidetracked for a minute with the available anywhere thing (you can sign into Google Reader from anywhere, too, and I believe they recently updated it so you can download stories onto your laptop, say, when you're somewhere with a connection - in an airport - and then read them offline later (when you're flying two miles above any wireless networks.)
Below is a video that explains, quickly (under 4 minutes) and amusingly (with the patter! I loves teh patter) how RSS readers work (Google Reader is the example they use, but there are others) and tells you, in a non-technical sort of way, how to set one up for yourself.
Best tip from the video? "It's addictive, so be careful." Truer words were never.
