I voted relevant.
Even if there are 50 participant, I think we should have it. Why? Because, face to face interactions matters. I think we should choose the venue wisely and spend less. I hope we are doing that already. This year is was reasonably timed for me, but at the last moment my wife's Algeria trip showed up. It is very hard of us to travel during school year, it is basically impossible if one of us is not in town.
I will try next year.
