Maybe, but practically every change Twitter makes is to make it look and work more like a Facebook timeline.
Given that Twitter is overrun with trolls, especially women-hating gamergate-style trolls, it's rapidly losing its value. See, for example http://femfreq.tumblr.com/post/132152537305/talking-publicly...
You don't get that on Facebook.
Both are useful, but Twitter is sticking to its domain, while Facebook tries to lure the user into dependency on as many levels as possible.
