Feedroll just surprised me with how easy it makes adding synidcated content to a site. I just added added Lockergnome's RSS and Atom tips to my site with just a few clicks. It is so easy that I expect to be changing the syndicated content that I offer on a regular basis. If you are looking to add syndicated content to your site, why not give this a try?
The question still remains "why add synidcated content? Doesn't it take viewers away from the site?" My comment is that readers come for content, and if I offer them lots of content options, they'll find me anyway. Besides as more readers rely on RSS readers to get their content, my lists and blog rolls will become increasingly less important. This is another place where -- we'll see what the future brings.
