You can use an RSS feed to fetch updates from websites you care about, and particularly ones that may not visit every day. This process is different than subscribing to emails--you won't be getting any more of those as a result of signing up for RSS feeds to follow some favorite sites.
Let's use this very blog for example. You might be interested in what posts are coming next but you don't know when I'm going to post. Since I don't offer email subscriptions (yet? :p ) your best bet to passively follow future tips and tricks would be to subscribe by
- Clicking the RSS Feed button, also on the right of this page. NOTE: May not work with Chrome :(
- After clicking you will be given an option to pick a specific "reader." I would suggest subscribing using Google Reader, only because it is especially convenient if you're already using a Google Account for Gmail or anything else. That said, I imagine RSS Readers across the board are more or less the same.
- Add more sites and check in to your Reader at your leisure.
If you're still looking for a more detailed description on RSS feeds I would recommend this post from Google and Feedburner.
