Twitter has done well releasing this and when I first saw it ages ago it looked neat and fairly professional.
However, like a pop song which has been completely overplayed on the radio it has become tired and frankly a bit annoying. It has its uses offline to quickly get a demo up and running but it shouldn't be used on a live site. At least not in its entirety.
If you have to use this for your project due to convenience or lack of design skills then do everyone a favor and mix it up a little bit. Change the colors on the buttons. Avoid the black bar running along the top of your website. Just don't look 100% like a vanilla bootstrap site.
Unless you're targeting developers or Silicon Valley who cares? Most people couldn't tell you the difference between a Bootstrap site or a non-bootstrap site, even if they could its unlikely they would actually care. As a dev who admittedly sucks at CSS I'll take better looking and clone-like (and cross-browser) over ugly and unique any day.
Also, check out oss/bootstrap/docs/download.html#variables a new feature in the docs that makes customizing really easy even for someone who doesn't know CSS!
It just looks like you chimed in to show the negative side, but didn't even check out the new code.
Thank you to anyone who worked on the project, 2.0 is awesome. Responsive design is nailed down, adding and removing components is even easier than before and the docs are awesome. Good stuff here.
If you look at iPhone or Mac or Windows application they looks the same as other application on particular platform and no one annoyed. Each application use same keyboard shortcuts and controls and frequently share same colors.
There is even UI recommendations for most of the platforms. You could use owner-drawn controls for sure but it usually they are used only if default controls are unsuitable for some task or in games.
In all fairness, what this proves is that there is a fairly large market for such packaged customization themes which are built thoughtfully and work on all resolutions.
I proposed names like @primaryColor, @primaryColorLight, @secondaryColor, etc, but the tickets were closed. Yes, it's a lot of work, but it must be done. If you can define your four colors and have Bootstrap look entirely different, it goes a long way to instant customization.
Any discussion on it will hopefully be at the HN thread I just submitted (http://news.ycombinator.com/item?id=3538053).
Instead, if they did a (or a few) authoritative themes with compass css with such good documentation as bootstrap and their theme works at all resolutions, I'm sure people will use that one too.
Some would say that it isn't a bad thing to have more of that on the web.
Some of our customers seem to have some difficulties finding information on pricing here, for instance: http://www.liberwriter.com/
If that navigation link were at the top in a small black band, it might as well be on Mars.
The point about pricing in particular is that there is a huge button in the middle of the page, and people are still not clicking it. My instincts are that a black bar at the top of the screen would be nearly invisible to these people, many of whom are more advanced in their years than the average HN user.
As for the "view plans and prices, get started" I believe a smaller button that is better positioned with a hover effect would get significantly better results. Even a simple change such as changing that text to something a little shorter like "Get Started Now", "View Plans" or " View Prices" will get you better results.
Ultimately I believe you would see significant improvements using bootstrap across your site. Some examples of what others have done with bootstrap can be found here http://builtwithbootstrap.com
