I go cycling, but I like gentle outings (20 miles, 12 mph...), so I'm very unlikely to join a cycling club and do long fast group rides, even if I was fit enough. However, if would be nice to know if there are other cyclists in my local area doing similar types of ride, who might fancy meeting up for a ride.
So my suggestion is to extend follow suggestions to include people in the local area with a similar activity profile. They could then use the existing follow and activity comment facility to arrange to ride together, if both parties wanted to, or block following if they preferred to ride or run alone.
