I love C and Lua, and both are untrendy, long-lasting languages that don't attract particular crowds, and it means that when I produce something with them, unlike the trendier side of software development, it will actually last and run 5 years from now.
I think branding like this is a double edged sword. It says, "We're trendy and attractive, but established," and at the same time it says, "We guarantee you're going to love our mascot plushies and the high quality $15 decal stickers you're going to slap on your $1,299 MacBook Pro that you just got back from the Apple Store over a stuck key repair."
Now, I do not endorse a complete neglect for cohesiveness and consistency. In the case of Go, it has an interesting interplay between sophistication and fun - this was a perfect opportunity to make an xkcd style cartoony brand that conveyed both simultaneously. Instead what we got is an infuriating bullshit that looks like one of those stock logo/branding templates I can buy for $19.95. Sigh.
