My experience is a few years old, but it probably hasn't changed much. It really depends what you are looking for. The enterprise forum in general is more on the business side than the hacker side, in my experience. I never really made any great connections there, but that may just be me being too introverted. Note that there is also the free e-club (http://web.mit.edu/e-club/ http://web.mit.edu/e-club/) and the free 100K competition (http://www.mit100k.org/ http://www.mit100k.org/) at MIT.
