Google Wave added two new feedback extensions to the extensions gallery, you no longer have to repurpose Yes/No/Maybe:
- With Pollo Gadget you can gather opinions from colleagues about work conditions (like the Greek food in the cafe, yum), ask conference attendees about their background, or vote on the best submissions in a contest.
- Likey gadget displays "Like|Dislike", the number of participants that have clicked "Like" or "Dislike", and an indicator of what you clicked. You can use Likey to figure out which items people like on a restaurant menu, vote on movies you're thinking of watching with friends, or learn what your teammates think about specific product feature requests.
- Waffle gadget lets users add on potential dates, indicate "yes/no/maybe" for each date, and then summarizes the results for each date. And yes, it does look a bit like a Waffle. You could use it to decide when to watch a movie, figure out when your team members are going on vacation, or schedule a round of beer nights.
