https://botbot.me/freenode/bitcoin-core-dev/2016-09-29/?msg=73959763&page=4 (to show an example of a recent meeting)
Currently the IRC group is being used for discussion regarding development, but this doesn't allow for people in all time-zones to participate (e.g. it's 2am in Thailand).
Also the bitcoin-core-dev group is being used to discuss protocol changes, which obviously affects all other Bitcoin variants, so perhaps such topics ought to be moved to non-core specific areas.
Raising this here as I am unaware of a more appropriate venue currently to raise this, as it is currently a core-specific issue (given it's the core specific chat room).
Any suggestions on a better forum/software to use for this? Ideally it ought to be something that allows likes/dislikes (as GitHub already has) to previous suggestions - doesn't rely on everyone being present at the same time - and ideally allows for threaded conversations and sub-topics to occur, yet allowing for an overall agenda to persist, perhaps with options to vote on proposals and keep a tally of votes, as well as the membership/status of participants (GitHub also already does this).
Overall, given the criteria I am inclined to think GitHub may already be the best venue, but I do hope that others can agree that a venue that allows participants from varying timezones and allows inclusion of non-core participants for non-core issues is desirable.
So, this is two issues really - a better venue for bitcoin core discussion, and a better venue for overall bitcoin development discussion.
