I think this falls into the same jurisdiction as Wappr does (http://news.ycombinator.com/item?id=1123173 if you missed that conversation), where you're aggregating info from people that may not want it used as such. I know that this is trying to prove a point, and yes, the Twitter account for pleaserobme sends tweets to people who get listed on the site, but it's still a little heavy handed.
Yes, and it's reminiscent of the Buzz launch as well. People seem to think that "publicly available" is a binary state, i.e. either X is public (1) or it's not (0). By that logic, if X is already public then aggregating/broadcasting it is fair game: you're not putting it through a state change, only going from 1 to 1. I think this is a mistake. There are clearly degrees here.
