Definitely agree with the problem on the page for account creation. I think when you click "join now" you should be directed to a page with only two options:
1- Get a free account, but it might take a week to get approved.
2-Buy an account(cheap) to instantly use HIVE.
Once the user selects one of the options he then goes on a new page with the different possible services that sell accounts.
Other issues are harder to solve, and probably need video tutorials for wallet downloads and how to use them. It is doable though and definitely can be integrated down the line.
I am sure that the devs have thought about this but they are swamped at the moment. The chain is not even two month old.
