I think we should talk to more and more people in person to onboard SN. If they even stay 1 or two days on SN, I'm sure they can't avoid the learning that SN imparts. So far I've referred 22 people but active people are only those who remained active at least for two or three days. Those who just signed up but didn't bother to read, I didn't ask them to do because they aren't readers.
