I will say it's nice to have them actually honour keywords in searches that google has made harder and harder to discover and seems to ignore at will (inurl: site: etc)

The funniest one for me in google is +"foo" they decided people didn't actually mean it, so they changed it to +""foo"" - then when we all started doing that, they made the new secret "yes I really want that string" to be +"""foo"""
