I remember hearing about a Xerox research lab that had a whole room where the walls were all whiteboard.<p>They had a celling mounted camera that would scan the walls.
They also had a markup language that the camera OCR software would pick up. So for example if they drew a P in a square, it would print out that wall to the printer.
If they wrote an e-mail address in a square it would e-mail a photo of the whiteboard to that e-mail address.<p>This was 7 or 8 years ago. I wonder if they still use this system.
This is my first time hearing about DirectedEdge: very cool stuff!<p>I watched the video and it looks like you guys have a great thing going on. I'd like to make a suggestion, if I may: prove that this isn't just for "similar users also bought". Prove that everybody should be doing recommendations for practically anything.<p>Here's one idea: call the Reddit guys. Use your recommendation engine to recommend articles, subreddits, and users I might like based on my up-votes. Ask them if they would be willing to show "Recommendations Powered by DirectedEdge.com" on there. Hit it out of the park with one partner and you'll have other people lining up to use your platform!
Photographing the whiteboard and emailing the photo(s) to everyone who was at the meeting is a great tool for remembering what was discussed and decided. I'm always surprised at how few people do it. If your whiteboard isn't big enough and you have to erase it halfway through, you do need the presence of mind to take a picture before rubbing it out. Leave the camera by the eraser.
As a method of keeping a whiteboard for posterity, also consider MagicWhiteBoard :: <a href="http://www.magicwhiteboard.co.uk/" rel="nofollow">http://www.magicwhiteboard.co.uk/</a><p>You do your whiteboarding, and can peel them off and save them for later.<p>[I do not work for MagicWhiteBoard in any capacity]
Directed Edge is pretty cool. So far, though, I think we've been hearing a lot about their graph database, and not much about how they're actually going to do recommendations. Personally, I think the latter is the harder problem.
The vision sounds a lot like Loomia... though it looks like they've come to focus on content/publishing sites, retail or indeed 'anything' seemed the earlier focus.
