I've searched for it, but can't find the links anymore unfortunately. However, every couple of months a new show hn makes it to the front page with finding like-minded people, making new friends etc.

If you search on Angel list for "meet like-minded people" and you will find some. Here some from the top of my head Spontacts, Sporty, Spots-app, Woofound, Highlight, Sonar.me, Vingle. This article is also very insightful http://techcrunch.com/2013/05/07/ambient-location-didnt-work...
