Hiring people helps, but it doesn't always solve the problem.

You can hire someone to look at it and say "this is what i'd fix" and they'd have some good opinions. However there's people that've been using this dev portal for a lot longer than the new hire and those people have been using it long enough to have a fair assesment on their pain points with the current site.

Also i dig your suggestions personally however this is more about their dev portal and not entirely their site (although i do wish to see more of steem and more people on it) but IMO it seems outside the scope of this post
