Interesting, will be cool to see the different uses for the follow person system.
I used it a bit today, and its kind of sad that you can not follow people unless they are your steam friends. (Or allow different settings).
Also, it might be able to be improved with highlighting the user you're following somehow in game, maybe add a distance to the user above or under their name and tag.
Basically it could be improved, but it's a nice feature and has some potential!
Thanks for the update!
