It’s interesting to read the comments here. People seem to be either strongly for, or strongly against this tapping feature. I bet the split correlates to whether all your friends live in the same town as you.

For me, I already know what the handful of people who live in my little town are doing. I see them all the time. An app like this is for keeping up for the rest of my friends who live out of town and I might only see in person every few years.
