CBS MarketWatch's Bambi Francisco is riffing again today on Google's need to have an instant-messaging service to increase its stickiness. It's a credible idea but it just scratches the surface in terms of Google's shopping list. My take is Google also needs to seriously think about expanding into the RSS search engine (Technorati) and VOIP (Skype?) markets. That said, there is no way Google or anyone else for that matter is going to pay $3 billion for Skype. That's just silly speculation by Robert Cringely, who should know better. If Google wants to go from being a very lucrative one-trick pony, it needs to get serious about diversification. Say what you want but Google Maps, Froogle, Gmail and Okrut are interesting intellectual exercises for the company's developers - not home run business hits. Google has the cash and cache to make a big, bold move. Skype would cost its some cash but it would not only be a key strategic move but prevent rivals (News Corp., Comcast, Yahoo, Microsoft?) from going after it.
