Hi, 

This impellent deadline could be took with enthusiasm from people that are anxious to experiment with new protocols and platforms that can replicate mailing lists and offer, in theory, better solutions.
I think this enthusiasm is totally positive and I encourage them to work on that ideas.

But I also think that this mailing list fills a very particoular need of communication in the bitcoin space. 
The stream of ideas hosted here is strictly dependant on the form it assumes when formalized in the peculiar format of mails-threads. 
Migrating these technical discussions to a forum or a pseudo-group-chat wouldn't replace this mailing list, even if the moderators behind and most of the participants would be the same.
It would eventually be a new and unstable solution, with no-guarantee to preserve the same goals reached here.

Today exist a lot of places where people can exchange ideas about bitcoin;
if new platforms will emerge as better suited to hosts BIP drafts and technical discussions, people will move organically through them.
In my opinion, "finding a new platform" is only marginally correlated to our main topic here.


If our problem is helping decide the "future of bitcoin-dev mailing list", the only two solutions to me appear to tautologically be:

1) Give continuity to bitcoin-dev mailing list with a ready drop-in replacement. 

2) Don't give continuity the bitcoin-dev mailing list.


In the case 1) a solution could be find a new host for the mailing list and work around the problems exposed.

In the case 2) is possible to do nothing OR to propose a new solution as a sort of "spiritual continuation" of bitcoin-dev mailing list, and eventually see if people will converge on it.


Understanding all the difficulty behind the management of the bitcoin-dev mailing list, I think it has worked very well for many years, and I hope it will work for the years to come.
I also want to say thanks to all the people behind this mailing list for all your work and effort.
