Yeah no kidding!

In the past I had my own CSS 'framework' and it worked reasonably well, but if you actually look at bootstrap's code to see all the edge cases and weird vendor-specific features they address at some point I realized I can't keep up with this craziness and just let somebody at least deal with the baseline. It's WAAAAY easier than managing even one weird behavior that takes hours to work around sometimes :-)

That said tweaking bootstrap is not trivial either. Stuff is scattered all over the place, and finding the right place to tweak and make changes can be difficult too. If you've ever rebuilt a theme to a different color scheme you'll find out that you end up writing a ton of CSS of your own. But at least you're generally just overriding and using the base behavior that you can count on to be solid.
