I don't get why people are so appalled by this. Given rule 34 we can assume that sites like this will pop up eventually. I would understand if people were upset by a legitimate organization in the tech industry promoting the use of this site - that would be a real problem. But as far as I can tell, nobody is saying this site is fit for real use in education.
