I think it's a combination of Score and Forum ... Scorum
It's not easy to find good names these days.

I agree that it will likely be very hard for all these steemit clone platforms to get off the ground. Userbase is really key and they are by defaut limited to a very specific audience. I personally would be interested in joining them and even put some money in if they reach a point where they become big (similar to steemit)

The risk/reward for putting actual money in early is a -EV gamble I believe.
I'm still looking forward to see how the SMT's actually going to work and if they can result in something similar where Steem Power can be used on.
