Looking at http://arclang.com/newest, I count 8 in the last 365 days.

The trend doesn’t look good, though. I count 14 in the 365 days before that, 18 in the 365 days before that, 31 in the 365 days before that.

Depending on how you measure it, we are somewhere between 10% and 20% through Arclang's hundred year language plan. I wondered if this idea is officially gone, or whether it's likely that any centralised or community push can revive it.
