City Explorer
I completed the City Explorer in September. Aside from the wonderful all-black picture captured from my app (which I used to print up a t-shirt), there was no recognition from Citibike or Lyft.
I think it would be wise for Lyft to publicize this, as it will attract other riders to complete the task. A number of past City Explorers had newspaper articles written about them.
The simplest way to do this is a leaderboard. I get that the number of stations, and the number of stations remaining, is computed from the ride history each time I click on "view profile", so it's not as easy as the bike angel leaderboard. But it shouldn't be that difficult to compute a leaderboard once per month.
Hoping this or something like it gets done. I'm any case, I'll be back on the road this fall when the expansion happens.
