Hi @themeanbean, the QR code will be useful.

It would good to also have some form of 'fallback' system for those that don't use QR codes. Otherwise there is always the risk of undercounting the success rate of the leaflets.

With standard web based promotions we would use a unique url on the promo material that we would track visits to via Google Analytics, but I don't think there would be anyway of emulating that on steemit?

So it would need some more pro-active approach of telling new signers to visit a particular account perhaps to get a little signup reward. That would have a small cost but would encourage engagement and retention.

Maybe new signers could be offered a mentor or steem-buddy to help them through the very confusing first few weeks.

I've experienced that sort of mentoring system in online games and it has been very useful.

I am a bit of a noob still so this may all be in place and I haven't spotted it. Forgive my ignorance if that is case.
