Asymmetric follow (a la Twitter)?

I’m working on a social network for a particular community that will require asymmetric follow (like Twitter) vs. friending (like Facebook). I’ve installed the BuddyPress Follower plugin and it seems to work fine except for its associated widget which only displays ‘following’ while leaving out ‘followers’. I’m sure that correcting this is fairly straightforward, but my PHP skills are limited. Has anyone else out there come across this problem and perhaps figured out a solution? I’d be super grateful for any tips…
