I keep getting ads in my Gmail (web interface) for Masters' programs or programs in education.
Are you kidding me?
Google reads all my email, this blog is in a Google property, I have a Google Scholar page so they should know I have a PhD, really, and I have a Google Sites page.
Serving me ads like this makes no sense at all. None. No, really, it doesn't. It's indefensible. But yet, they do it.
