Retracted; found the feature buried some where.
I know twitter users could argue both ways on this one...
On one hand, having such a listing will allow you to find out who are your true friends (reciprocal followers). On the other, if you're following people randomly just hoping they'd follow you back, then you'd really need to re-think your following strategy.
In all cases, I think the option of whether or not to have this page should be admin selectable. So if it is not already there, can you please consider adding it?
