RSSs are in my opinion, one of the best things that have come along in a while.
RSS (Rich Site Summary) is a format for delivering regularly changing web content. Many news-related sites, weblogs and other online publishers syndicate their content as an RSS Feed to whoever wants it. (http://www.whatisrss.com/)
The great thing about RSS is that you can get information on a regular basis to see what has changed, updated, or even “how to” on multiple websites and topics that you are interested in. Some of my favorites come from Microsoft, these include tips and tools, online training, as well as some web design information on different software, scripting, etc. Even my Netflix queue has an RSS feed!
RSS’s are a brief description of the latest information, or updates whereever you have subscribed to. Because it is a brief outline, you don’t need to read through a ton of posts to find what you want, or read every email that someone sent to get the information you are looking for; ie: mailing lists. I would waste most of my day going through a list of 30 emails to find one that actually had some information that I wanted/needed. With the RSS I can look and see if it is something I want to check out or not.
This video explains it all! I love it!
