Facebook new live time update feature...how good it is? Does facebook coping Twitter?

Hi Friends,

What your views are on facebook lates updates...live time update, share thing, pictures enlarge and others. I think facebook is now coping features from Google ( image enlargement thing & share one), live time update ( from twitter)...is it because of changes required or because of competition faced from other sites?

 

its just an evolution thing....you adopt what works best to keep people interested
