They pivoted to become the location data powering major mobile apps (ex. Twitter). Dealing with small business to monetize is hard. You can't charge the consumer because you need the checkin and to get enough of a sales team on the ground in the SMB market is astronomical. If you ask me if they should bring back checkin to core 4sq app, not sure if it's fully relevant anymore. Their new ad platform pretty much just monitors you as you walk. So geoloc ads. I like it, and if they get enough SMB advertisers they can be a good acquisition target.
