I just looked up the acquisition and it looks like it was around February of this year. I met my girlfriend on Hinge the previous October, and after a series of mostly fruitless and/or boring dates on both Tinder and Bumble she was my only in-person meeting from Hinge, but even in the few short weeks I used that app, the message rate seemed much higher as well as the quality of conversation. Sad to see that it's been degrading recently.
