New Feature Idea if it's not already in the works: threewords.me places (foursquare?). would leverage current users engagement to tag locations with a dead simple description. could keep users coming back, provide utility(value)to businesses, and make you some more money. email me (firstname.lastname@example.org) if you want more ideas, although it seems you have your hands full as it is. Good Luck!
Also, I don't know how time-intensive it would be, but it could be helpful to have some sort of drop-down box that initiates when users start typing in the three word spaces. Sort of like a google-instant-type thing. 5 synonyms pop up ranging from strong to weak. So if I started typing "h-o-", it would infer I was typing "hot" and (on the left, or strong side) it would have "blazing" and on the right(or weak side) it would have "warm". Or something of that nature. You get the picture. Might be easier for mobile folks to get the best possible description and faster.
