I never really hear any feedback on this arrangement from anyone though, the little feedback I have got so far suggests people appreciate that multiple parties have differing levels of control over the forum. The forum is not my top priority since I focus more on bitcoin.org, so if anyone has the feeling they would prefer theymos being fully responsible for bitcointalk.org, it would be good to at least hear that opinion expressed.
I consider Bitcointalk.org the identity of the forum nowadays. Its matured enough, and that is the name that will be known as. Yes, the forum has changed domains before, but this was in its infancy. In a semi relatable circumstance our (wales) national stadium recently had its name changed, however the general Welsh population still considers it to be the old name, and refuse to call it by its new which has undoubtedly caused confusion when tourists have asked where the principality stadium is, and the local people refer to it as the millennium stadium.
The point is the previous domain change was very much in the forums infancy, and didn't impact too many users. However, now that the forum has matured it would definitely be an annoyance. I for one like to mitigate any issues as much as possible, and would be looking to solutions to make sure that a domain change would be incredibly unlikely.
Currently, we have yourself who is in control of Bitcointalk.org, but god forbid if something happened to yourself, or in the hypothetical situation where you point the domain to something else other than the forum then it could be an issue. Approaching this unlikely issue with a multi signature sort of approach would be the best idea in my opinion. Having multiple trustworthy users which sign whenever an action is taken with the domain. Setting this up wouldn't be without its issues of course, but definitely something to take a look at.
This multi signature approach would also reduce the potential of a user disappearing, because the rest of the parties could still recover the domain.
I think I've mentioned it before but I'll do it again: the current setup has worked for many years, and I have no reason to assume it will "break" any time soon. So I'm totally fine with leaving everything as it is now.
However, for the very long term, assuming Bitcoin and this forum will last, there should be either a permanent solution or at least an order of succession. A hundred years from now, none of us will be posting here, but it would be really cool if Bitcoin and this forum are still around, and someone takes care of it to ensure this very message is still available!
If a order of succession was to be established who would be the deciding factor on selecting the successors? Order of succession would be a highly debatable topic I'm sure, and I'm not sure if theymos or a community vote would be the better choice here.
