Actually I have another important idea. One that has been discussed countless times and does not even require a hardfork.

I am talking about Steem Wiki (including hardfork wiki) in english, regularly updated with info about the top dapps and all the recent developments.
Preferably on the front page as well as on steem.com with an annoyingly big link, so nobody can miss it.

Why? Because our official wikipedia entry is absolute trash.

This is the german steem-wiki. Not bad, but certainly not complete info. Just for getting an idea...
