"If it bleeds it leads" got you down?

I came across this site the other day called Good News Now. It is an aggregator site that highlights only good news for the day. Some of the articles are really uplifting. This made me think that because of the prevalence of aggregator news sites in the new media, journalists should try not only to get the attention of their readers, but also the attention of news aggregator sites. Anyone could create an aggregator site that could become extremely popular like the Huffington Post or the Drudge Report have become.
