Agreed. Here is what I will do:

1. Set up an LN node, despite getting wrecked twice in the past running one.

2. Go back to providing liquidity on JM, which I had only run for a short time because of all of its quirks and rough edges.

3. Pledge 1M sats to any credible and organized effort to revitalize JM.

Any other suggestions for what a pleb can do are welcome.
