meh Facebook wont just roll over and die, there are millions and millions of users, much more then Myspace ever dreamed of when they were on top of the social media niche. G+ isnt even close to catching up. I seen alot of people on Facebook stating how much they hated the timeline thing, and before that it was the layout change people complained about and so on and so on. People dont like change its simple as that. If you dont have a FB account well good for you i guess, but it is also good for webmasters as well as a promotional tool for your site, so i guess you are missing out on all of those search results in google
