@wanderer Interesting question. One which I have been grappling with myself.
With no advertising budget, much of the marketing will be down to @ned and @dan running the PR side of. So far we we have seen user numbers grow from 4,700 to 18,300 in 4 weeks. We have started to see some pain attached to the hack with the website going off line for periods, which explains the peaks and troughs here

There is a lot of variables here, but I would expect to slowly make our way towards 50,000 users over the coming 2-3 months.
Hopefully somewhere between hitting 50,000 users and growing towards 100,000 users, we could see some locational critical mass begin to be hit which could really propel the platform forward.
This is all predicated on the price of Steem maintain at lease 50% of it's current price
Also very subjective and complete opinion..
