Circa 4 weeks ago I had the same core idea! I think this is very interesting to be able to follow people you respect or are interested in one way or another, regardless of the platform where you find them. A kind of global Twitter. This has potential to become the new version of a social network. Kudos on executing it

PS: Initially I thought that the killer platform to adopt such a thing would be keybase! I even thought of tweeting to them, but then the idea just fleeted away. Oh well..
