Before making a single edit, Tropedia EXPECTS our site policy and manual of style to be followed. Failure to do so may result in deletion of contributions and blocks of users who refuse to learn to do so. Our policies can be reviewed here.
All images MUST now have proper attribution, those who neglect to assign at least the "fair use" licensing to an image may have it deleted. All new pages should use the preloadable templates feature on the edit page to add the appropriate basic page markup. Pages that don't do this will be subject to deletion, with or without explanation.
All new trope pages will be made with the "Trope Workshop" found on the "Troper Tools" menu and worked on until they have at least three examples. The Trope workshop specific templates can then be removed and it will be regarded as a regular trope page after being moved to the Main namespace. THIS SHOULD BE WORKING NOW, REPORT ANY ISSUES TO Janna2000, SelfCloak or RRabbit42. DON'T MAKE PAGES MANUALLY UNLESS A TEMPLATE IS BROKEN, AND REPORT IT THAT IS THE CASE. PAGES WILL BE DELETED OTHERWISE IF THEY ARE MISSING BASIC MARKUP.
I'm currently in college and taking a ton of computer science and math related courses, and about twice a week I learn something that makes an Xkcd suddenly become absolutely brilliant. --Elan
Likewise, I was learning integrals when I read this strip. Reading the info text was probably the first time I laughed out loud reading something on the internet. — Sandbylur
For April 1st 2012, Randell deviced dozens of different strips that would show up based on the users location, browser, OS, and home domain. The alt-text was identical for all of them and said:
'Umwelt is the idea that because their senses pick up on different things, different animals in the same ecosystem actually live in very different worlds. Everything about you shapes the world you inhabit--from your ideology to your glasses prescription to your browser window size.'
No, sometimes it would say "your web browser", and there may have been a few other permutations.
