I know they are different but also they are very related. By implementing a reputation system in UbuntuForums you could harmonize points here and there. This would integrate both communities and avoid those competitive people to isolate from UbuntuForums (no idea the extent of this but I guess there is some of it). There are tons of questions never solved in UbuntuForums and that means people coming to AskUbuntu. That is plainly inefficient. Since there will not be a centralize system (different owners), why not to integrate them?

Certainly, beans are not the proper measure to associate with reputation since you gain beans for anything but UbuntuForums could implement a differentiated system where users "like" one answer if solved they problem. Do you think it would be a good idea?

PS: Amazing Askubuntu and reputation are tags not created yet!
