If you read the announcement, this is already pretty tightly integrated into IG, assuming you link your IG account to your Facebook Dating profile. 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.
