You know about OS-tans, right? They started as fanart of operating systems personified as anime babes. Over time the concept grew beyond operating systems and companies started making their own. Microsoft has a few "official" -tans marketed in Japan and other Asian countries, but I'm pretty sure "Internet Explorer-tan" is the first one that's also marketed to Western audiences. I've been following her Tumblr blog for a while now and I've been fascinated by how much thought has been put into the Microsoft Anime Girl Canon.
Anyway, now that Internet Explorer is being phased out in favor of Microsoft Edge, I naturally assumed the Internet Explorer-tan character would commit seppuku the day Windows 10 ships, and a new browser-tan would take her place. Instead, they're simply renaming her. You can't do that! That's like a total violation of OS-tan rules! It doesn't communicate the idea that Edge is an entirely new browser! It peeves me off real bad
