The Washington Post has a nice analysis of the changes in Top 20 sites over the last two decades
“The first year here is 1996, when the web was … young. Several of the top 20 sites were college sites, thanks to colleges having invested early in the internet. AOL and Yahoo were there too, as they have been ever since. Mostly, however, the list is garbage nonsense like “GNN” and “Teleport,” which we don’t even know what they are. Notice the ascent of Excite and CNET. They’ll be interesting in the next part of the graph.”
"The techies in attendance were starry-eyed for all things mobile, picking Nitobi’sPhoneGap, an open-source tool for building mobile apps, as the People’s Choice winner. Life-tracking site zeaLOG was a close second."
Features to make GMail even more helpful such as Goggles, which makes you solve math to make sure you are still awake or sober before you send mail ; the addict feature forces you to take a 15 minute break by blocking your screen; and still others useful such as the recent addition of texting from a chat session.

the AFC East from signing up to use it this year. The software passed
an unexpected test when Brett Favre was traded to the Jets right before
training camp and needed a crash course in the Jets offense. The team

and a handful of high school teams, are also using the system.
At the heart of Huddle is the ability to watch game footage from the
comfort of one's couch. Teams capture and log their video using their
standard methods; Huddle seamlessly, and immediately, offers the video
on its shared site. Just like the Blackberry freed the businessman from
the cube, Huddle lets players leave the video room. Coaches can log
into their accounts and tag video with telestrations,
voice, and text. They can then send those clips to players for their
review or even create tests, to check just how well a player knows the
playbook or realizes his in-game mistakes. Diagrams can be created
using Xbox-like technology and then linked to video examples."
"While e-commerce sites tend to derive recommendations from a mix of information
