Where to start w/consensus voting app for Yahoo groups?
I'm thinking about writing a consensus building tool for Yahoo groups that use iterative voting passes to let people build a consensus about subjects they're discussing. It would be sort of like a Yahoo group poll, except that users could write-in choices and change their votes as new interesting choices get added.
My question is, where do I start with Yahoo's various API's? Which ones would be the best to use?
Would the Yahoo! Application Platform be the best way to go? Maybe in combination with OAuth, YML, and YSQL? I'm reading the various documentation, but some pointers on where to start my save me some time.
