Often we receive tweets with which we don't agree and we want to poll our followers about their opinions. Ideally we should be able to attach a poll to a tweet without leaving Twitter. With this thoughts in mind I made PollAll.me. It allows to attach a poll to a tweet as easy as send a tweet.
If you don't agree with a tweet, just type @pollall ? in your reply and receive a poll with default question and quotation of the replied tweet. Or you can provide your own questions and answers for a poll, just reply with a tweet like:
@pollall Will Java replace C in 5 years: Yes, No, Never?
PollAll.me runs on Google App Engine. I deployed three projects on GAE already and I like it very much for the robustness and stability. Server side is wrote on Python with Jinja2 as template engine. On client-side I use JQuery, Bootstrap and CanJS, fantastic JavaScript framework to which I switched after using Backbone.js.
