I agree with you about many of the layer 2 tokens. Many are created without a clear purpose (other than have fun) or an understanding of the work involved to maintain momentum and build a community.
Having said that, there are some tokens with a solid backing and plan and a leadership team. I would include SPI and EDS among those.
I've just written elsewhere that I feel there were a lot of unrealistic expectations about ListNerds, and that there is something to be said for holding the basic free subscription which provides a weekly email.
Appreciate your decision, though, and I wish you well.
