To add: it doesn't encourage actual conversation, it's more like QA kind of thing.
I don't really get what the point of tumblr is. Like, why use Tumblr instead of other blogging sites?
I use tumblr because I like the layouts on your blog and the customization and I actually don't really know any other blogging sites.
I also am still in there because of actual original content, like photography, some comics, art and other stuff. And it's pretty easy to follow those blogs.
Who are you talking to right now? Who is it you think you see? Do you know how much I post in a year? I mean, even if I told you, you wouldn't believe it. Do you know what would happen if I suddenly decided to stop posting? A post count big enough that it could be listed by the NSA goes belly up. Disappears! It ceases to exist without me. No, you clearly don't know who you're talking to, so let me clue you in. I am not the one shitposting. I AM the shitposting! A guy opens a thread and gets spammed and you think that of me? No. I am the one who spams!
