fastcoin had the same idea of speed of transfers as well but has long since died..
Fastcoin uses scrypt algo, and does not have PoS, also the devs+community is not the same.
the devs+ community has worked so well for doge..
It worked well until Scrypt Asics arrived, same with all the Scrypt coins no matter how good community it had before. Same reason many of them is looking at changing their algorithms. UTC does not have that problem.

Also Doge transfer times was horrible.
