Besides blogs & wikis, one of the greatest advances brought on by Web 2.0 is RSS feeds.

Used to, if you wanted to find news about something you had to go to google or yahoo, do your search, and then go down a list of web pages to see if one might have what you were looking for.

But, with RSS feeds, you can make that information find you.  Most websites, including this one, have RSS feeds that you can put into a RSS aggregator or you can create a google, yahoo, etc. (the list is on the right) account and link them to your RSS feeds.

Any time a website with RSS capability posts something new, your RSS reader will let you know about it.
