This absolutely needs to happen!! When I first joined steem I'll admit I was a bit disappointed to find out that I had to buy bitcoins first then send the bitcoins over and wait for the transaction to go through then eventually get the steem, having to fork over the transaction fees all along the way.
If we can get it to where you can safely and quickly buy steem directly with USD I think that will attract a ton more members and investors and will tremendously help the current ones.
As soon as my university semester is over I'll help out in any way I can, although I'm still new to the whole crypto/blockchain tech. At the very least I'll gladly test the system in every way that I can and constantly give feedback when needed.
