OPoll is a completely free, open and public survey voting platform. After registering as an OPoll member, you can issue surveys on any topic that interests you - current affairs opinions, hobbies, market research etc. In addition to providing single voting units, OPoll can also organize multiple voting units together to generate an online survey form, which can also be embedded into a Blog via code call. The only small defect is that the voting period is up to 30 days at most, but the overall service is still very excellent despite this minor flaw. Below are some voting examples.
