digital "curators" choose and present things related to a specific topic and context. They "curate", as opposed to "aggregate", which implies plain collecting with little or no value add. Viewed in this context, Google search does the latter, not the former. So, who curates? The Huffington Post, or HuffPo, is one high-profile example and, it appears, a highly-valued one too, going by AOL numbers-crunchers who forked out US$315 million (S$396.9 million) to acquire it. Accolades have also come in for Arianna Huffington's team of contributors and more than 3,000 bloggers - from politicians to celebrities to think-tankers. The website was named second among the 25 best blogs of 2009 by Time magazine, and most powerful blog in the world by The Observer.
