How is this different from Bootstrap (http://twitter.github.io/bootstrap/)?
If you don't do the comparison yourself, you're at risk of losing out.
Their primary job is not marketing. Their primary job is to build the framework.
Why do you think things like Y Combinator exists? They do some work others aren't willing to and others lose out because of it.
It's to the developer's benefit to tell you why his product is good, but it's not their duty. These guys worked on and released a free product for you. You can choose to use it if you want but they don't owe you anything or an explanation of why it's better than Bootstrap.
The developers put reasonable efforts in building the website, introducing the project so that people will adopt it, so I think an article comparing their project with Bootstrap definitely helps with adoption.
And yes, corporate governance regarding browsers does weigh in heavily in mass-market sites here, so we have to make sure the layouts don't break - Ink enables delivering a predictable, working layout that degrades gracefully down to IE7 for that reason.
Seriously now, yes, Bootstrap has always had forms. But as a developer who merely dabbles in design, I personally prefer Ink's markup because it's responsive off the bat (at least compared to BS 2.0, haven't tried 3.0).

Personally, I like it. It's nice to have competition :)
