Also, bootstrap uses normalize now, not reset. This poster should make a little more effort to understand before criticizing. It's obviously a useful framework as many find it very useful. Coding and html css for a complex is not something a developer wants to do unless they have very, very good expertise in front end development. I think bootstrap is great for developers who aren't front end experts, but aren't necessarily bad developers. Maybe specializing in back end work, database, web server side stuff. Using bootstrap frees you up to focus on things that matter more for your app, and you don't have to worry about typography, typeahead, grid systems, etc. It's one of many options that satisfy this need, such as Zurb's Foundation.
