WHAT IS A BLOG?

Is this like a journal or something? I might overshare... HAHAHA. It's my first time using this website. They said it was like myspace. I've also never used myspace :D. Maybe I'll overshare here haha... I'm attending my online class rn but I'm not really listening because my teacher doesn't teach and she just tells stories. 85% stories and 15% teaching. IDK, she asks me questions but I just don't open my mic and pretend that I can't hear her. SUPER BORING TBH. It's really cool that I can choose who sees what I write here. I just saw this website on TikTok. It seemed cool. I'm still figuring out how to use this though.
