As a non-smoker currently reading Allen Carr's "Easyway" in order to find a solution against my procrastination problem, I completely understand the parallel but I don't agree. Facebook might be OP's habit to kill time but this works equally good with any Twitter, Reddit, or even HN. The problem (for addicts) is that those websites constantly stream some short new items, easily read, easily forgotten. It's the same dynamic indeed as going for a smoke instead of doing some work but it's not exclusive to facebook and facebook is not killing you.
