Yes this looks like a marathon effort which will flourish on the blockchain too :)

I ran my own query, and am not sure if this (fairly simple query) is displayed elsewhere. I assume one of these sites will have it, maybe someone else can help...

Personally, I like this list over the followers list as I think it gives a more accurate reflection of your following, and what they can potentially give to you. (Users who have left generally have little/no SP - that's my theory)

Cheers!
