Yeah there's nothing to really "learn" from that sub whatsoever.      Weirdly enough the most helpful thing I picked up about Tinder was from the red pill subreddit, God help them. Really just started using the line "Hey, just thought you were cute and had to say hello" with every match. That breaks more ice that trying to be overly clever and cute with some cringy opener. That's really how I started talking with my current gf, along with just being incredibly lucky.
