Tumblr. 

The absolute terrifying black void in which I throw away countless hours of my limited time on this planet that both makes me

a. Question my own existence

b. Lay on the ground flopping around in a spasm like situation because of the amazing GIF of my favorite fandom.

Tumblr. is a both amzing and horrible world of its own.

Tumblr 

An inverted social network where the more ridiculous you look the cooler you are.

You dress like a twat... you'd be popular on Tumblr

Tumblr 

A microblogging website founded by David Karp. While, for the most part, it is true that you can post (in text, photo, quote, link, chat, audio, or video form) whatever you want without fear of retaliation, this is not always the case. Oftentimes, if your opinion differs from somebody else's, you receive anonymous hate mail (using Tumblr's messaging feature with an option to make yourself anonymous, called "anon" by the users) that is unrelenting. Tumblr really is a great place to go onto, but only as long as you don't say "no" to someone else's interests or opinions. Your blog is your own and should not have to be subject to the radical fanaticism of other users.

User (posting an opinion about the "Fabranger" ship, one of many interests Tumblr users have: "Fabranger? Quinn Fabray and Hermione Granger? No. Just no. They're not even in the same series. I completely support LGBT, but... no. Hermione is as straight as a Ticonderoga pencil."

Other users with differing opinions: "Stupid. Bitch. Pussy. You're a disgrace to LGBT supporters. You're so smallminded."
