I think the advice is still relevant and there are a lot of new users. There has been talk of the site guiding new users on what steps they should take, but I guess that is still being worked on. At some point it needs to go multi-lingual too. Steemit is growing fast, but there are billions of potential users out there who will need help getting started.
Oh gosh, billions?! Now i'm even finding it hard to go through "new" already lol
I think some of the existing features will not scale. There's a challenge in handling massive numbers, but Ned says he is up for that
