I think we have enough infrastructure already in place which facilitates easy contacting and/or email forwarding. We really don't need this list. No one is on 24hr call you know.
You could mention:
Bug-tracker - good place to report problems with our sites (That is ones we have control over - not Github)
Forum - best place to send DM to folks if necessary. Email notifications are immediate.
Mailing lists - lede-dev is a good start if the conversation is development related.
OK to list our names - just mention the methods for contact from the list above. If it is so urgent to contact someone and you are unwilling to register on the forum or bug-tracker - too bad. I prefer not to have my email addresses plastered all over the place - they are easy enough to get a hold of.- I have for years felt like I am the king-of-spam AND I do have good anti-spam filtering.
It's less intuitive for the general user to look at mailing lists or bug tracker than this link, but I think that thess is correct that the forum mail function should suffice.
I do think that there may be some "generic" contacts that can be added to this list, most importantly one to report the site (forum) is down.
