I like the way it highlights a quote without having to deal with a bunch of actual quotation marks. If something you want to quote includes quotation marks it can be confusing to read (especially on mobile). It also reminds me of commenting out things when programming.

I saw similar punctuation on "Forensic Files" used by a serial killer. Not that anyone who uses odd quotes is a serial killer. ~~Just sayin'~~
