I wholeheartedly agree. This is one of my major gripes with web apps replacing native ones. I never have to figure out what's a button or a tab on a native app. It seems these two concepts get reinvented ad nauseum with web design, such that I have a hard time figuring out what to interact with or how on many sites. This tends to end up in a cyclic argument of "well, if it were well-designed, it'd be obvious." But, if it looked the same, it'd be even more obvious. The other half to this is I care more about content & usability than aesthetics. Bootstrap lets me produce and consume content more readily. So, I'm a fan.
