This is probably the easiest place to start. Find an RSS feed and display it on your website. Why should you do this? Read on and find out.
RSS in social media is mostly about taking one or more RSS feeds of stories you like and posting them out to your social media sites. This can happen automatically as the item appears, or it can be held an you can decide which items get posted. This gathers lots of convenient content at your fingertips to be shared out to others.
All of these services work basically the same way: A user signs up for your mailing list and the mailing service periodically looks at your RSS feed for new items and emails them to your subscribers. Sounds simple, right? Apparently not so much.
