What can we do to educate and grow the community?

We need an official wiki that has all the important information and is kept up-to-date. Right now everything is scattered around and it's really hard for a newbie to find all the right facts about Steem. Fortunately it's coming, but Steemit hasn't still found a person to take care of that task. If you know somebody who is good at explaining things about blockchain, please contact @ned.

We should start to think how we will let subcommunities emerge. If Steem grows bigger than what we are now, it's really hard to have just one community. There will be simply too much users and posts.

Now we have tags and personal feed, but that's not going to be enough. There should be a way how users can create strong subcommunities in Steem, where they don't need to care what other users are doing in other subcommunities. The existence of a strong community will create incentive to keep using Steem even if somebody can't produce posts that are rewarded well with money.

I'd encourage everybody to think outside the box for a while and ponder how the content feed could be personalized optimally for every user. How would you design Steemit.com if it didn't exist yet (there was only the Steem blockchain without UI)?

Languages are one important factor here. Users should be able to see only the languages that they choose to see. For that to happen, there needs to be a standardized way to indicate which language the post is written in. My suggestion is to use ISO 639-3 for that.
