So what are the next steps for nem?
What would you like them to be? 
If you haven't yet, come join us and propose projects, ideas etc. and help us make NEM something never before seen in the history of men! :-D
I believe that the first next step now is the publishing of the whitepaper.
Hopefully shortly after we are going to see mobile app.
Continuous strenghtening of the network, nodes etc.
Continuous refinement and adding of the features line n-x multisig, asset exchange etc.
Remember that by each day that NEM network and security isn't breached it gives NEM project validity.
NEM - starts with you.
Really. Make a good enough case and the devs will build it. They are very open-minded, flexible and have a pretty good ear for the communty's voice. Having many times switched directions from community feedback.
