Maybe its because i've been coding seriously for about 8 months, but why would not using a framework make things more complex/limit you?

I thought the whole idea behind 12 startups in 12 months was to practice/get as many bootstrapped online business going fast

I mean i understand if one is still learning coding that frameworks would do you no good but in this case thats not really the purpose.....
