What do you mean "back"? Blogs very well exist. I read a number of them. I write one, for heaven's sake (probably a dozen people or so reads it but it's ok that's how it is meant to be). They are living in the shadow of facebooks and twitters of the world, but who cares. Turns out, popularity is not everything, and unless you plan to make living out of it (which I most definitely don't) you don't need to compete with anybody on anything.
