Pretty cool. Do you have any particular use-cases in mind? I could imagine it rolled into a bigger suite of social media management tools for brands. It could help them follow the people who follow them on other channels or something. Not sure about the consumer use-case, though.
Thanks!
Not sure who would use it :P
It was just a fun project.
But I do think there should exist such a service which aggregates and organises all social accounts.
