Check out dkg's blog post where he talks about how New York City's 2009 Summer Youth Employment Program requires Internet Explorer in order to apply online.

He points out that "Even downloading the pdf version of the application to print out from the site is impossible under non-IE browsers because the actual pdf link is wrapped in some IE-only javascript."

Everyone should read the post and if you live in NYC, please follow his suggestions for further action: call 311 and file an official complaint against the NYC Dept. of Youth and Community Development (DYCD) or even call the number on the application page (1-800-246-4646) and demand that City services be built on public and open standards and not locked to use of any one proprietary system.
