There is no one definitive answer to this question. Some people believe that a blog is social media, while others believe that it is not.
Ultimately, it depends on the definition of social media that each person uses.
Some people consider social media to be any type of online platform where users can interact with each other. This could include platforms like Facebook, Twitter, and Google+.
Others consider social media to be only platforms like Facebook and Twitter where users can share content with their friends.
In my opinion, a blog is social media if it allows readers to share and interact with each other. A blog is not social media if it is only used to write about personal experiences and does not allow readers to share or interact with each other.
