@paul There's already this post, do you mean a post for after the talk? Then maybe we can write a post-event update.

Oops, I think I must have somehow missed that SciDataCon was already posted.

Let's morph this issue to be a request for either a "live" report from the conference or a post-conference write-up (whichever best fits).
