We've tried so hard to promote LN though...
I know, it's not your fault, Lightning is just a failed project, but people refuse to accept that.
My prediction is that in 10 years LN won't even exist anymore.
Good idea. In the past we tried launching a forum, but it wasn't a success.
Just add quick feedback with stars rating, and maybe short text, but it's not going to be easy to prevent fake reviews.
