How is this different to existing conferences (both hardware and software) where there are a ton of booths and table and people showcasing what they do? Products, services, startups and non-startups alike... Maybe I'm not understanding the difference. Not saying that not differing would affect attendance in any way but I have a hard time answering if I'm not sure I see the personal value proposition. Especially if its just to see what other startups are up to, quite a number of conferences like that around here (probably different for other locations).
