Sorry for the lack of replies; I've been away helping run a tournament.
I definitely like the idea of a "technique of the week" or something similar. Perhaps we could do an over-arching "theme" per month or quarter and then the techniques can be related to that. So perhaps one period could be "ashi waza", another could be "turnovers" etc. and then each week the technique would be related to that.
I'm not sure if having weekly question threads (like WBW) would make sense yet due to the low traffic. I think it is better to just have people feel comfortable to ask questions directly here so they don't get lost or missed.
For competition lists I don't know what the best way to do that would be. Perhaps at this early stage it would be best to just make separate posts, but if they become too much then we could look at some sort of consolidation.
Club lists is a great idea. I wouldn't want just a large list of clubs from everywhere dumped here, but something where members can say "here is a club I go to or have visited that I recommend" would be a nice feature. Any thoughts on the best way to do this in Lemmy?
