What I find most interesting are all of the different uses people are dreaming up for something like Grazr. It definitely motivates me to not let people down.
A couple of unique uses that have been pointed out to me: Russell Beattie uses Grazr in a microsoft standalone HTM application. Only works in windows but it's pretty neat.
Someone ("chicagosage") created a yubnub 'web command line' command for creating a quick grazr panel.
