Sandeep Singhal asked an interesting question at the begining of his talk: How many of you want to be entrepreneurs and how many of you are already one? A large number of hands went up on the first and very few on the second. Clearly unconferences attract aspirants. This is evidenced also by naivette that one sees in the questions asked etc.
The good news is that a lot of the aspiring entrepreneurs at least at Barcamp Bangalore were working at an idea or had a ready concept or were looking to launch. Good deal flow for VCs such as Sandeep.
