I don't think that Yahoo's decision necessarily nullifies RSS feeds. The thing with Yahoo, Google and a couple of other syndicators is that they have pretty clear usage guidlines about their RSS feeds. They are basically for personal and non-commercial use.
The good news is that there are plenty of other RSS providers, and you aren't relegated to only using Yahoo feeds with the module. You could use RSS feeds from
Big News NetworkTopix NetAbout.com The New York Times and a few other news sources that are basically begging people to syndicate their headlines.
You may not get all the pretty pictures that Yahoo rendered, but you don't have to worry about lawsuits, either.
