I think that social networks today are more successful and more popular than blogs, but I must say that I am part of those people who always love Blogs.
Almost since 2007, I met with blogs and blogging, for me it was awesome. I started blogging now. I have too many blogs, blogs about music, a Legal blog, and now a Personal Blog.
Social networks do not appeal to me, Except Twitter and Instagram, but always say, blog and nothing else.
