That would be Mike Milken, who is financing a business advice site called Bizmore. The idea is to provide a kind of forum for executives at small and mid-sized companies. Users pose questions and others weigh in with answers. It's not a new idea, but the Milken name does make it stand out. From the NYT's Bits:

The company is a subsidiary of Vistage International, an executive coaching and networking organization with about 15,000 members who pay up to $13,000 a year to attend meetings, hobnob with fellow execs and get one-on-one leadership counseling. Vistage, based in San Diego, is partly owned by Mr. Milken, the philanthropist and former junk bond king. Mr. Milken sits on Vistage's board and was instrumental in the founding and funding of Bizmore, the companies say. (So far, Vistage has committed about $10 million in seed funding.)
