Ask HN: Foursquare: Why check-ins in Swarm?

Dear Foursquare -

First off, I have great admiration for your company, how you handle your technology and your data science. I think you have much greater market potential with some of these features (specifically physical crowdsourcing and recommendation engines). With all of that said, I have a question about your branding.

Why did you move check-ins to Swarm rather than leaving them in Foursquare, and move all new features to Swarm? Anybody that I talk to about why they don't use Foursquare says "I don't care about check-ins." To the public FOURSQUARE = CHECK-INS. Changing this takes months and millions of dollars. Why not, instead, say "Swarm is our new product that takes care of <new stuff>" and Foursquare maintains the check-ins.

Thanks!
