There is a common complain that bitcoin-dev is too noisy.  The response plan is to narrow the focus of the list to near term technical changes to the bitcoin protocol and its implementations (bitcoin core, btcd, ...)

Debates over bitcoin philosophy, broader context, etc. will start seeing grumpy list admins squawk about "off-topic!"

It is a fair criticism, though, that "take it elsewhere!" needs to have some place as a suggested destination.  The proposal is to create a second list, bitcoin-tech-discuss or perhaps just 'bitcoin', with a more general rubric.  This split has served IRC well and generally manages to keep the noise down to a productive level.  We want this list to achieve that same goal; if bitcoin-dev is not productive then it's not useful.
