Neat. I was just looking at Hamming distance on wikipedia and in the see also section of the page it lists similarity (mathematics)...and word golf (word ladder). When I connected with similarity it reads "Similar" redirects here. For the place in India, see Shimla.

Shmila

Shimla is often referred to as the "Queen of Hills"

Anyway..thought it was an interesting connection.
similar~ more of the same.
