Foursquare recently updated its core app, eliminating the check-in functionality (you can still checkin using the companies Swarm app), turning its main app into a recommendation engine.
Foursquare Tips play a big part in its recommendation platform, surfacing keywords and phrases that tie into your interests and queries. But not all tips are meant to be permanently displayed on a venue's listing. For example, some tips are tied to specific promotions that only occur during a specific time of year. With that in mind, the new Foursquare now offers an option to set an expiriation date for a tip.
The process for creating a tip that expires is simple, requiring a couple of extra taps during the creation process.
You can leave a tip at anytime by tapping on the tip button in the top-right corner of the app. Select the venue you'd like to leave a tip at from your check-in history, and compose your tip. Just below the text field you will see a small text label of "Forever." Tap on that, which will bring up a list of options to set as an expiration date. If the default options do not satisfy your requirements, the "Until This Date..." will allow you to set a custom date.
Once you're finished, save your tip and marvel at your increased Foursquare Expertise.
As someone who relies on Foursquare's recommendations, I have to say this feature was something I never specifically thought of, but probably should have. Often, tips from two or three years ago are no longer relevant and only clutter up a venue's page. I just hope users take advantage of it and start setting expiration dates.
