But what even is a blog?

Today I learned there were blogs. I dont know what they are for. Is there any merit for blog posts? I do not know. Do people read through blog posts? Are mods forced to read through them? There are so many questions, and as I sit here pondering them I realize I could spend this time completing quests or restocking. And now that I am coming to the end of my blog post, I think I will do that.
