I've complained in the past about the untargetted advertising on Yahoo Mail, huge 200x200 or more banners for University of Phoenix Online. (Right now, 425x600 pixels for a credit check).
That's alright, they don't have all that much information about me, I'll forgive the untargetted advertising, although I could deal without the huge dimensions.
Well Facebook, who does know a lot about me and about its target audience, right now has an ad up for Strayer University, a multi campus, questionable quality institution. But I'm already at college! So why put college ads on a website you must already be in college to see? They do a few grad programs, like IS, MBA, MIS, Accounting, but it just seems like a poor use of a university's money to advertise an online university to one of the top schools in the country.
