Tagmap is something I've been working on for a bit to try to help solve the problem of how difficult it is for people to meet like-minded individuals near them (or just on the Internet in general sometimes). The general concept is that users tag themselves with their communities and interests, and are then placed onto a map for each tag that they have. Users are also presented with a list of other users that are closest to or most similar to them (based on tags and some other metrics).

For an example of a Tagmap that has a lot more users than the hackernews one (linked above) at the time of writing, check out https://tagmap.io/tag/slatestarcodex, which is for readers of a certain blog that many of you might recognize if you browse HN often.

Love any feedback via any medium including here.
