Facebook is now in lockdown mode according to insiders. This is when the company is developing major features. Many have suggested that the company is reacting to pressure from Google and their new social networking efforts to displace facebook.
No-one knows exactly what Facebook is working on, but something sizeable is going to need to be done to keep users coming back. Fact is google has so many internet properties such as Google.com and its Gmail service, photo sharing Picasa and many others. Google after much inertia is now getting the idea that it must be more social to head of Facebook.
Could we see Facebook developing search or its email facility?
