*dons finance/stats nerd cap for a moment*
There's also a question of selection bias, however. The survey weights all opinions equally, including those from people with no particularly strong opinions one way or another who may or may not spend much time in the guitar forums, while a poll, which might solicit fewer responses, will tend to self-select respondants who 1.) spend the most time in the forum, and 2.) have the strongest opinions. If those 20 people who bother voting represent 75% of the Guitar forum regulars, then that's actually arguably a more representative sample than a survey of thousands where those 20 opinions are weighted amongst people who check this forum once a week tops, or not at all.

I don't have any particularly strong feelings one way or another - I think both sides have valid points. That said, the one piece of feedback I would like to offer is this - if we do end up permanently splitting the guitars forum into "Electric stringed instruments" and "acoustic stringed instruments," I'd rather see it as a separate forum rather than a subforum, so the most recent post for each is visible, rather than the most recent post from whichever one was last updated.
