Polling your users is probably a very smart thing to do, as long as it's worded right and not obtrusive. The best monetization features have some sort of utility built in for the user. ie- Google paid search ads show you items that are relevant to what you're searching for, a freemium account on dropbox gives you more storage space,etc.
