I appreciate their effort in subbing, it just the number of subber went down in a short time. I think it got something to do with summer (vacation and stuff).
However general popularity also affected by how fast a sub came out, like when one of my friend saw a sub for certain anime came out less than 12 hours he said "hey thats pretty quick, must be popular, let me see em" ^^.
Well I still have the patience to wait for quality sub (since my PC doesn't like mkv)
PS: Luckily I know Japanese a bit, so I could understand 50-60% of the episode.
