All of these good points. And no worries about being critical, it's helpful and I'm not going to take feedback personally. I appreciate the help :)

Note that it might not be so easy to acquire STEEM if you're a fresh steemit user. And there will be many of those.
This is something else to think about - how to make the account registration and management easier to use than what is currently in steemit. We don't want only the technically savvy communities here, do we? :)

This is a huge issue and I haven't even begun to tackle it. It reaches far outside the scope of chainBB and into the entire Steem ecosystem. Initially I'm targeting existing Steem users as the core user - but in order to expand beyond that, the issue of account creation is going to need solving.

Unfortunately the fact that new accounts require funding puts a massive barrier up. There's been a lot of talk on how to fix this but no solution has been implemented yet.
