Syndication... which one should I use?

PDF versionRSS vs ATOM   So which one of these two will be the future? Which one should you use? Here is a nice little article from InterWingly detailing the main differences between RSS 2.0 and ATOM 1.0 http://www.intertwingly.net/wiki/pie/Rss20AndAtom10Compared I reckon ATOM will see some further adoption and growth due to the APP (ATOM Publishing Protocol) as well as to the fact that it came to life due to incompatible versions of RSS. Unless, of course, like many other technologies, some new RSS killer comes out over the next year ot two and overtake these 2 standards.
