Interesting idea. I commented on the blog already, but this thread feels so empty. ;)
I'm the founder of Goals.com, and while Goals is still way early in its development, I'd be happy to have you compare it to a competitor in the task/goal management space. But regardless of what you write about, my interest is piqued. Good to see what someone else thinks just from a product development standpoint: how is someone going to be tearing down my app?
Best of luck with this. If you'd like more info on Goals, feel free to email me at josh@goals.com.
P.S. Nice choice of Posterous. It's what I chose for the Goals blog for the time being.
