YAHOO NEWS — May 30 — Classmates (10 years old, 40 million members) will turn users favorites links into advertiser links. e.g. a visitor to a profile listing Shakira as a favorite artist could click on 'Shakira' to hear a song for free, courtesy of RealNetworks' Rhapsody, which sponsors the section. United Online bought Classmates.com for $100 million in October 2004.
