I like the concept, after a brief look at the site here are my thoughts:

1) The site has a clean look but is fairly boring and bland. Get some more color and design going. It's hard to separate content visually etc.

2) As a side project it looks cool but I don't see the startup potential. Where's the money going to come from? Ads on floor plans? Your click thrus will be low I fear.

3) How do you get more content? What's the motivation for me or for a conference center to get their floor plan on your site? I'm not sure it solves a problem that existed before. Was navigation of conferences and hotels that big of an issue?

Some ideas: 1) Make mobile access possible a bigger selling point. If I can get to it from my iphone or blackberry etc then that makes it a bit more useful.

2) Find your way to draw in more content.

3) Find your line to profit. Is it a directory for conventions + this nifty layout and mapping utility? Do you rent a higher quality system for events willing to pay for it?

I'm not trying to cast dispersion and such, good luck on it :)

Nice logo, good pithy tagline. You need some variation in the background colors on the map.

Maybe needs more explanation of who will use this and how: planners, event hosting, exhibitors, guests. EG, "Going to FooCon? Looking for the Sony Booth?"

Overall, looks very nice. Good luck!

My good friend and I recently made our startup project public. I chose to make an interactive map of EclipseCon 2009 for an early demo since it has enough going on in a large space to make the demo interesting.

Also, if you have an iPhone, be sure try us out thru mobile Safari. We have an alternate iPhone UI.

We're prepared to support conferences at this point, but we've kept other indoor/custom mapping scenarios in mind while developing.

We would really appreciate any feedback you may have: ideas, layout, design, etc.

Thanks! Casey & Nassim http://floorspan.com
