Plaxo integrates Yahoo's search engine directly into the Outlook e-mail program. Under the deal with Yahoo, Plaxo will get paid for channeling people to Yahoo's search engine. The search box will be placed beside a Plaxo icon that sits atop Outlook.
I always wondered why Michael Moritz and Ram Shriram liked this company . Ya , its an interesting product , but it have no obvious way to monetize . IMHO they cannot monetize much even if they release a enterprise version with more bells and whistles! .
I dont think a search box in outlook (that too with just 2 million members) will bring in loads of money .
This goes in venture history with Friendster and Napster as an interesting product but without an viable business model :)
