Most of these are quite explicitly described in the documentation (img-responsive, nested columns, responsive grids, container-fluid are all very upfront in the documentation).
And on a UX note, I cannot see any advantage to the animated, slightly expanding prettyprint code boxes. I don't think this is a valuable piece of UI.
You could read about every grid detail, form & UI element and JS element in less than 20 minutes.
Thus, articles like this one have their place, and I for one thought it picked out some nice under-utilized pieces.
From the first bullet point in the "Grid System":
>Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.

I guess you might not think to look for it in the documentation, but if you don't think to look for it, that means you probably aren't using it, and don't need it... I still wouldn't really call any of these things tips or tricks, it's just actually reading the documentation of what framework you're using, which apparently people don't do?
I'm really not trying to poo-poo the article but you could pluck 10 random things from Bootstrap's relatively simple documentation and have the same thing.
Maybe if it were titled "cool things in Bootstrap" instead of being presented as "tricks."
I'd call a trick something that is not part of the documentation core, something that has unexpected effect or behavior that was unintended initially.
None of those would apply here.
Either way, I didn't say such "tricks" are without peril - surely a number of jQuery "tricks," even those that were eventually canonized, have been broken over the years as the library updates.
If on the other hand you use a conventional definition of trick, "a clever or particular way of doing something", then the post is indeed about a set of tricks.
Also, for the pedants: in many English-speaking communities, "tips n tricks" is simply slang for "miscellaneous useful bits".
Finally, general props to scotch.io for being a better-than-average blog.
