Scanlators are entitled to have at least one page to themselves. As long as they don't bring up politics, religion or other edgy shit, I couldn't care less.
I don't care if a scan group tries to make a funny joke at the end of the chapter, but if I had to chose, I prefer the ones with informative/explanation at the end. For example, I loved the work made by AMA Scans at the Slow Motion wo Mou Ichido, because this series has a lot of japanese pop culture references and it's very interessing to point out. They made a better job than the english scanlation group with that.
