40,000th Kancolle post on Danbooru.

I still remember the day when the tag had less than 300 posts. It wasn't very long ago!

At this point, kantai_collection is now the third (if we will not count the original) most populated copyright tag here in Danbooru. Still behind vocaloid, and of course touhou that has reached more than 400,000 posts recently.
