Walt Mossberg has put together a brief overview on using RSS. According to Mike Manuel:

In the span of 14 days we've seen a powerful one-two punch in support of social media by two of the most influential business publications in the world. You can bet a lot more companies are paying attention now...

I still think that for many people their introduction to RSS won't be via the name RSS, it will be via integrated RSS readers on newspaper or portal sites. This is something I wrote about earlier.

For many net users their first introduction to RSS will be via a newspapers 'new subscription service' (RSS to the rest of us). I assume that many of the papers will make some mention of RSS, but for the most part they will come up with a catchy name for their news readers. Users will not even know they are using RSS. Ask a tech novice what ISP they use and you may get a blank stare, ask them what online service they use and you'll get an answer.

After you read Mossberg's article, check out the guide I wrote earlier this year on utilizing RSS.
