Looks like a great app, but does anyone else see the shocking similarities between http://www.peashootapp.com/ and http://www.basecamphq.com/ Open them in two tabs and click back and forth. Is there any connection between YongFook and 37s?
I agree that the shopping experience is extremely close to that of 37 signals, but given that the thing he's selling (URL shortener + analytics + campaign/goal monitor) is unrelated to any current 37 Signals products, it doesn't feel "too close" or disingenuous to me.
Also, he's the primary developer of the open source activity stream/ blogging tool Sweetcron, so there's another reason I give him the benefit of the doubt. He seems to have a healthy respect for the creative process.
