I don't think blogging as a whole is dead at all, I think that if you have a niche to write about (computer science/programming as an example :P ), your blog will be as popular as it would have been 5/6 years ago as long as you put enough work into it.
With regards to personal/life blogs, I think they have became less popular due to VLogs and YouTube so having a popular blog about your own life will be difficult.
