If a sale of the company is your exit strategy, think again. Yahoo cant get meaningful search numbers and their technology is worthless. Now the email client is no longer secure as Yahoo cant get a grip on the XSS attacks (security chief resigned with no replacement). Market share is being lost to Gmail.
In the Yahoo grave yard lie auctions, maps, briefcase, pictures and shopping. All it takes is one competitor and Yahoo folds its tent. It's just a news aggregation site.
