Spokk.io

Spokk is a social platform that helps you gather honest opinions from people all over the world. You can use it to get your skills, ideas, creations (Blogs, designs, art, music, photos, videos, inventions, etc.) and even your persona improved through crowdsourced opinions. This is different from other social networks because while the identity of the people who ask questions are shown, the identities of the people who provide the opinions via voting, rating or commenting are masked via a nickname. Anonymity helps people open up and be more honest when providing their opinions.
You can rate the quality of the anonymous opinions, these ratings will be mapped to the profile of the opinion provider - thus giving them credibility and a reputation. Reward points will also be allocated for higher quality opinions which can be redeemed later on.
