@CFComm you changed the colours on the blog!  Wow!

is the sentiment of that tweet positive or negative?

you can't answer that without knowing my frame of mind

you have no idea if I said:

"you changed the colours on the blog!  Wow!", while muttering to myself "you've gotta be freakin' kidding me!  the million and one things that need to be fixed and they waste time with pretty colours??"

or if I said:

"you changed the colours on the blog!  Wow!", while thinking to myself "good job!  they have such talented graphic artists!"

and THAT, boys and girls, is why sentiment tasks should NEVER be counted in GA

Otherwise, the TAs should take their work down the street to Psychics-R-Us where their motto is "We KNOW what you're thinking!"
