Firstly because newcomers by definition won't be familiar with steemit.

Secondly, because it allows for better structuring and organisation of important infrastructural information (i.e. what devs are up to, new clients, blockchain forks) which is imperative for transparency.

Thirdly, because people encountering problems with Steem clients or with its blockchain can be helped more readily by devs/community helpers.

I agree .... Why not take advantage of an existing paltform to serve the steem community and attract new users to Steemit.... Good Idea!
