It doesn't say that it's over of conversation, we either meet right now or forget. Feel free to continue conversation online, it's just call to action, showing initiative. It's easier to respond to initiative, rather than initiate. And it's easier to convince someone to accept an offer face-to-face rather by messaging. We are social creatures after all.
It solves the issue of finding someone whos vision is aligned to yours.
A random note for coffee doesnt work that well for me tbh.
