Isn't that the point? If you are not interested enough to chat with that other person for mere three days, chances that you'll be interested in each other in the long term are slim.

It's just a very efficient, very selective filter. And it should filter out the majority of potential matches :(

Chatting with someone you don’t know over text is hard. You somehow have to capture their interest while having no idea what they’re interested in. In person, it’s much easier to get over this initial hump as you can try a bunch of topics quickly until you find one that’s interests both of you, and get much better feedback on the form of body language.

Yes, a text chat misses a ton of non-verbal cues. A video chat could work better.
