Love the ideas - asking ppl to do a bio for free is a good idea...put some seeders in the bio area "how did you hear about SN/bitcoin" "how long have you know about Bitcoin" "do you stack other cryptos and why?" If someone has been around for ages then seeding them from several users may not be as impactful as a total noob.

Also push them to review the FAQ section as I've had to refer back to it several times the past few a noob to the space even posting the pictures can be tricky for someone who doesn't code - an example might help. Maybe add what the sats\replies means next to each user?
