There are still are many people (like some who have given answers in this thread) who have never been to a bootcamp, know nothing about them, and continue to shit on them just because it is a different way of doing things. On the other hand, I have heard of some bootcamps basically just doing things you could do online, so YMMV. I dropped out of college and enrolled, and I am currently writing code for a living, so these programs definitely produce value despite what ignorant people may say.
The bootcamp I personally take incredibly seriously is Hack Reactor. I applied and had a great interview, but they told me to reapply again because my js wasn't were it needed to be for their bootcamp (which is fair, as I have focused way more energy on ruby/rails). I took that as a challenge, and I will be having my second interview in the next month, and I hope to go spring of 2015.
Hack Reactor seriously produces top notch people, rivaling that of many CS degree programs in my opinion. The instructors are incredible, the founders are very empathetic who have been in the position of many people coming to the program, and the students are all top notch. I could not think of any better way to spend 12-24 weeks.
