Certainly a shame.
I didn't really go to Moe much, but had those occasions when I was looking for a Highress of something, and that was always the place to go.

Danbooru is a pain, and it's coming close to 4chan with all it's crap.
Same goes for Sankaku, I only 'like' it there, because of the strange articles, and the rather funny members.

So, Kona will probably get an even higher increase in members now that Moe is down.
