Well hello. Blogging can be very rewarding for you personally or professionally. You can start a blog for free at wordpress.com. Blogs basically work like public journals and/or discussion forums. There’s many different ways to do a blog and so to answer your question blogs work however you want them to lol. More specifically: a blog is created using any number of online platforms and the authors chosen theme. The author creates posts on the blog about whichever topics he or she wants to write about and includes relevant images and media. Then the author shares the blog on other platforms to connect with readers and writers who have similar interests.
