to subscribe to blog feeds, you need a reader such as google reader. the point of a reader is that it allows you to read multiple blogs all in a single location. the main advantage is that it saves you the time and effort of having to visit each blog one at a time just to see whether they've been updated since you last visited.
another advantage is that--since it's so much faster and easier to check them all at once--it's feasible to check them all more frequently, thus allowing you to find new posts much sooner after they are posted.
and yet another advantage is that (once you've subscribed to the feeds) you don't have to remember any links, e.g. "blog.t-rev.net". with an online reader such as google's, i can sit down at any computer connected to the internet, log in, and check all the blogs to which i'm subscribed. otherwise i would need bookmarks or favorites to remember the locations of them all for me.
update 2008-08-14: the address of my blog's feed is changing. you can subscibe to the new feed now at http://blog.t-rev.net/atom.php or http://blog.t-rev.net/xml-rss2.php
