I don’t get their strategy. Why are they patching on to Facebook like this? Would this dating feature not be better strategically in Instagram? Facebook is rotten in the minds of users but IG is not yet.
Of course, that means you probably need to have a Facebook profile. And in that regard you have a valid point. Nowadays I'm pretty certain that most of the types of people I'd want to connect with have dropped their FB profile but still maintain an IG profile.
But I suspect we underestimate the number of people who are still quite active on FB and have maybe only heard of IG. The older, less tech savvy social media users out there still want to date too.
Of course, the pool of potential people you can date is "those on Facebook", so that's hilarious and compounds existing problems with echo chambers.
The only things I use mine for are 1) using FB Messenger (lite) to communicate with some other people who use that, and 2) selling some of my crap on FB Marketplace.
