What did you guys expect? You don't even come across these names here on this forum. If you ask people here which pool do they use, you will most likely get "minergaaate" or "extremepooool". Honestly, nobody gives a sh*t about those small pools. Furthermore, they don't even know about them, because they're too lazy to check page 1.
Sad but true...
I think the main reasons why the pools are small that, in the first, they is no good promotion and, in the second, the pools were created a lot later after Minergate and Extreme pools. So, if there would be good promotional campaign the situation could change. BTW Xmining is good to mine pool, IMO, but tastes differ
