I'd love to see @pharesim's Hive Invite toolset worked into front ends like PeakD and Hive.blog, so that more average users feel comfortable creating accounts.
We should turn our weakness into a strength and actually market Hive as requiring you to be referred/invited by another user. Centralized sites at launch often use that as a hook to build buzz and a sense of exclusivity while controlling their onboarding.
I think I saw @howo mention working on making account creation tokens transferable? This could be a big help as current users ask around for spares to onboard a friend or two.
I'm not working on it right now but it's on my todo list.
