I used to think RSS feeds are a thing of the past. I was wrong, I didn't understand the concept at first.
What are RSS Feeds?
Rich Site Summary. According to wikipedia, it used to be RDF Site Summary or Really Simple Syndication - don't know what that means, but anyways, what is it used for?
What does it do?
RSS feed from a website will automatically receive updates whenever the site has a new content - no need to manually check the site.
You will need an aggregator or 'reader' to be 'subscribed' to a website. Apparently you will have to copy the RSS feed link from the site, paste it in the aggregator to be able to recieve this updates.
Structure
RSS is XML-formatted plain text.
This example shown above was taken from wikipedia, shows the basic example feed content.
Do you need RSS feeds for your site?
I will let you decide for yourself. I think it is a matter of 'do you want visitors to visit your site manually for updates?' or 'do you want visitors to be told of updates then visit your site?'.
