Recently spotted on Ho Plaza.
The point this poster is trying to make: Cornell workers, i.e. cleaners, kitchen staff, etc, should get a rise despite the economic climate and should generally earn more. I can't really judge on that because I don't know much about the details but of course I think the cleaners should earn a fair salary.
But what is funny about this is that it highlights a little known fact. The domains www.contractforcornell.org is not the same as contractforcornell.org. While the latter is a second level domain, the former (with www.) is, strictly speaking, a subdomain of the latter. Other subdomains of contractforcornell.org might be something.contractforcornell.org or getadecent.contractforcornell.org. Technically www.contractforcornell.org and contractforcornell.org are different and some people configure their server in a way that it only responds to one of both. In this case the server only responds to www.contractforcornell.org. Omitting the www. on the poster is therefore a bad idea.
