I’d agree with the concensus, although it’s always good to mix some of your own unique content on pages where RSS feeds are bought in.
Regarding syndicating your stuff out, while I can see Alex’s point, I’d say that if you just syndicate out headlines and a bit of content, you are less likely to get people taking it up in the gambling sector. People tend to be looking for meaty content. I personally think it’s better to syndicate full articles but make sure you include a link to your site in the feed, and make it a condition for using the feed that he link remains intact.
