If I'd added a '/s' tag to those comments, it would have spoiled it, wouldn't it? Part of what made it funny was that I played it straight, and people believed I was sincere almost to the end - or beyond.
But now I fear I have led us far off topic. Back to our regularly scheduled discussion of Facebook, watchful defender of our privacy.
And the funniest part is, you're essentially describing jitter, which is timing differences between successfully and accurately reconstructed bits, and jitter can really wreck audio quality. So you only think you're being sarcastic, while on a higher level you're alluding to a deeper understanding of known audio playback issues that are quite real and legitimate :)
Sarcasm doesn't work in short text. It just causes confusion and adds nothing, since it just relies on the reader to decided whether the utterance means its face value or opposite.
Among other things it's virtually a HN rule at this point that the top voted post is critical. A purely positive post is a clear red flag and indicates sarcasm or some other snark.
