I've always thought that too many take first dates far too seriously. It should be a flirty laugh or an enjoyable day out, good company or any number of things which are fun and enjoyable but it is just meeting someone you don't know for the first time so there's is no telling where it might, or might not, go.
I don't think it makes much difference if you meet from an app, a website or down the pub. I get a reasonable amount of free time and I enjoy meeting people, even blind dates when you haven't any idea what each other look like. Does it matter? Is an hour or so out of a lifetime such a big deal?
