I really like the idea of kicking some life into the #introduceyourself tag, and particularly getting the various app front ends onboard with the importance of newcomers using it as an initial "toehold" here.
Steem seems to have four primary phases where support is particular important:
The initial bump where a nice recognition of an introductory post gives a newcomer inspiration.
A second bump to help new arrivals who "want to go somewhere" past RC worries, and to the point where their upvote adds more than ZERO to a post's rewards (currently seems to be about 40-50SP).
Stage 3 (where I currently am) which is getting to Minnowhood and potentially to where a standalone 100% upvote on a comment (for example) won't result in a "loss" to the dust threshold. Initially 500SP, and then on to currently (it seems) about 800-1000SP.
Fourth, where you become part of (at least) the frequently mentioned "Middle Class" where you have enough SP start actively giving back to those up at first point in this cycle, with curation and small delegations.
But I suppose what matters most in all this is encouraging those (which requires a lot of manual curation) who see Steem as a longer term opportunity, rather than just a glorified "cash machine" from which they liquidate and "export" their rewards, every week. I don't begrudge anything thinking it's cool to get pizza money every week, but I really do wish there was a way to "high level train" people to think of their Steem experience more as long term savings account, rather than just a place to make money.
I do really like the idea that OCD/OCDB help newcomers, particularly if that assistance serves to lay a more solid foundation in the community. It's great that we promote Steem externally, but that will only do so much unless "there is something here" worth both coming and staying for.
Well... I've gone on way too much, already!
