I always had the impression that a friendship or a similar type of relation should come first, to both gauge what the other person is like and to have time for both parties to build up a connection. Once that's done, consider where to go from there.

Granted, I have only had one 'romantic' relationship where I got romanced by a girl (didn't go anywhere precisely because it was so rushed), so I'm definitely inexperienced and probably far too naive to be giving takes. Still, I'm skeptical of Tinder and the idea of "let's make moves on a (near-)stranger", it just seems like a recipe for headache and breakups with only a low chance at a long-term relationship.
