The 'whoosh' thing can be funn iny but it can also be tedious and tiresome. Nibbles is an expert at it and rarely fails to choose an appropriate time and an apt tone.
Unfortunately not all who try it are so adept and their attempts are often feeble and predictable. It's these occasions when the whoosh thing seems pathetic and childish, and when it usually elicits moans and whines that the entire thing is actually rather unfunny.
Furthermore, regardless of whether the timing and application of the whoosh is apt and funny or poorly judged and unfunny, it is always a bit of an 'in-joke' and as such isn't very inclusive. This is relevant at a time when there are a number of new members on this board. They then need the whole thing explained, and then a genuine request for an explanation is treated with suspicion that it might in itself be a whoosh attempt. All rather tedious, I reckon.
I'm not against the whoosh, I just think that it is something that should be used sparingly and with a delicate touch. Having too many poorly executed whoosh attempts is an annoyance and detracts from the gems that are occasionally delivered.
In short, unless you're sure it's genuinely funny and well-timed, don't bother with a whoosh attempt and just leave it to nibbles.
