A blog is a website on which someone writes about their own personal opinions, activities, and any other experience that they have done. Sphere on the other hand is defined as something round solid figure with every point on its surface equidistant from its center. These two defined words taken as one is what you call a blogosphere. A blogosphere as what the Merriam Webster Dictionary says are personal websites and blogs collectively taken as a whole.
Nowadays, people connect with other people through different social media sites like Facebook, Twitter, and Instagram while some people choose to post on their blogs or their own websites. These blogs are considered as online journalism that interconnects with other people on the social media locally and even internationally. Blogosphere’s structure as I consider are us, who post on social media sites that give us infinite possibilities of sharing our thoughts and interests.
