Um, and if they do that, who takes the profits from the search engine? Microsoft, who has "invested" billions and billions of dollars and who would presumably like to recoup some or all of their losses, or Facebook? And if that's the case, how much value does that add to Facebook again? It's an interesting and open question, but methinks predictions that Facebook would get all of the profits, when Microsoft has put in the all or most of the capital costs of a money-losing search engine system, seem to be a little hard to believe, don't you think? And that's of course assuming Microsoft can be successful in search, which has yet to be seen at least from a business perspective...
