google hype tactics : "This is just an experiment to test concept feasibility", "This is unfinished, please consider that.", "This isn't a product, it's an experiment.", "Oh, it's just a side project of some employees, ignore that google owns it."
Seems entirely reasonable for these disclaimers to exist given that while Go is a legitimately open source project separate from Google, it is still strongly associated with Google in people's minds (not too surprisingly considering how many of the core Go team work at Google) and thus it wouldn't be hard to imagine some people getting the wrong idea of this somehow being Google's (or the Go team's) "official" answer to UIs in Go.
Well at least the title here on HN doesn't mention Google.
It did before, that was my bad. For me it makes a difference, even if they decline responsibility. Maybe they put it in the official account just to test the reception, and I for one would welcome an officially backed IU Go library with open arms.
There are many 20% time hobby projects by Googlers hosted on the /google GitHub account. Don't read to much into it.
