Hum, For my point of view Facebook didn't killed blog. Blog is used not only to show pictures of yourself, but writing. Nobody write on Facebook, they only share things. It's totally different, but hey anyway you can make your blog what you when that they are. Multiple account kill the service. You have at less 5 social media on every newspaper website. I don't use anymore twitter and I hope people will do it too. It's really a waste of time using 10 social media. I even don't use Facebook too.
