More helpful tip. If you're going to make a snarky comment, use the app so you know what the fuck you're talking about. Too many comments on hacker news are from people who are completely uninformed or just haven't taken any time with whatever it is they are commenting on. Disclaimer: I haven't tried the app personally but only because I can't stand apps posting on my Facebook or twitter stream.
side stepping the snarky comment debate sadly raging on. I too am unimpressed about sites or apps posting to my stream (thankfully this has evolved with time), yet I have a question...
what level of "detail/information/explanation" would you need to feel comfortable using a product which has functionality you can activate to use with your stream or not activate and it wouldn't hinder your personal use of the site.
