BLSH.it is a web browser extension. After installation, users are able to see a Shit button on their screen which is displaying the Shit rank of each page based on previous user's ranks. If a user hates page, he presses the button which increases the Shit rank of the page (so that others avoid browsing bad content) and (if user wants so) shares the page on his behalf on some of the social platforms.
Another feature we are working on is Facebook extension (button opposite of "like") which does the same as original browser extension, just with facebook content.
In the end we see our product as a global cross-pltform (web browser extension,social plugin, mobile app) ranking scheme for the whole internet content that allows a) users to get objective view of the content they are browsing, b) businesses - to have a platform that evaluates their usefulness and non-intrusiveness for users and c) a marketing platform that allows to use our technology as a white-label for their campaigns
