SOMN is interesting, they basically want to create a supercomputer by having several nodes connected to one another, this will help people "lease" computing power and do all sort of things (graphic designing, rendering, difficult calculations that require a lot of processing power, statistical models etc.) it's a great sector to be involved in but there is so much competition from other coins that are offering something similar, SOMN has in my opinion come a bit late to the party and it might find it difficult to gain some of that market share. It is however backed by a capable team and they do seem like they know what they are doing/talking about, I'm overal optimistic about the project but would closely monitor the competition if I was holding a significant stack.
