DEBRIS.COMgood for a laugh, or possibly an aneurysm

90 minutes, 13 companies, six minutes apiece. (Six minutes… sort of like the elevator pitch at Sears Tower.)

• SocialText, Ross Mayfield
  SocialText is the first wiki company. 30% of email is group communications… but email is not a great fit for that application. Wikis are superior (collaboration, searchability, revision, durability). SocialText is open-source. See also: wikiwyg.net — rich-text formatting for textarea fields; SynchroEdit — “a browser-based simultaneous multiuser editor, a form of same-time, different-place groupware.”

  Update: In a followup conversation, Ross Mayfield told me the 30% figure is apparently from a Gartner Group study. The term they used for this class of email is “occupational spam.”
  

• Rollyo, Dave Pell
  Roll your own search engine: enter urls to relevant sites. Presumably this works by filtering Yahoo’s search results based on the user’s “searchroll” domain list. “Yahoo provides the engine. we provide the steering wheel.”
• Joyent, Inc., David Young
  Some kind of groupware appliance. They’re launching a hosted version soon.
• Bunchball [no link because it locks up my browser], Rajat Paharia
  A development platform that provides the “plumbing” (infrastructure) for web-based interactive applications and games. The appeal is mostly to developers, and the friends of developers who come in to use the apps. Flash-based for now (additional UI toolkits in the works?).
• RealTravel, Ken Leeder
  Travel information site incorporating blogs, photo albums, google maps… goal is to provide real travel information written by real people. Share recommendations (or warnings) with the community. Looks like a well-integrated solution. The homepage links to good examples (“must-see travel blogs”).
• Zimbra, Satish Dharmara
  I thought this would be yet-another open-source dev platform (not that that’s a bad thing) but it turned into the best-received, most-applauded presentation. This happened during a demo of an email client built on the Zimbra suite. The message text was apparently scanned for recognizeable structured data types:
  • mousing over a URL pops up a thumbnail preview of the named website
  • mousing over a street address pops open a Google Map of the address
  • mousing over a date pops open the user’s calendar (another Zimbra app)
  • mousing over a phone number pops open a Skype window
  • mousing over a Fedex tracking number pops open a tracking application

  This was incredibly cool. I want this in my email client right now.

• Zvents, Ethan Stock
  I thought they said that Zvents has 3x as many events as their nearest competitor, but that doesn’t follow from the site’s Bay Area focus. Anyway, there is some neat functionality promised, like smart calendars, whizzy iframe integration of live event feeds into 3rd-party blogs (e.g., show area dynamic music-event listings on your music blog).
• KnowNow, Ron Rasmussen
  KnowHow is an unobtrusive notification system, a browser toolbar that pops up alerts based on your subscriptions. Basically it’s an RSS aggregator that delivers new data via instant messaging. But: IE/Win only. Bah.
• Orb, Ian McCarthy
  Access your digital content from anywhere. Run the client on your home PC, and stream audio/video to your office PC… or wifi MP3 player… or phone… There’s a file browser, too. Seems like a really cool thing, except that it’s also Windows only. Bah again.
• Wink, Michael Tanne
  Wink is a new search solution, based on leveraging human input or — dare I say? — the wisdom of crowds. One of their innovatians is a ranking system they call TagRank (a play on Google’s PageRank), which rates the quality of search results by tag popularity, or something along those lines. They’ll also allow users to manually rank search results.
• Allpeers, Matthew Gertner
  “transforming firefox into a web 2.0 development platform…” Share media files with friends and family via peer-to-peer networking. It’s free and cross-platform. I have no idea where the revenue stream is.
• Flock, Bart Decrem
  Flock is a new web browser with social interaction built in. It’s based on the Mozilla platform, which is a lot less insane than writing a browser from scratch. The alpha release will be out in a couple weeks, offering some neat features: the favorites button both makes a local bookmark and submits the URL to del.icio.us; it has a built-in RSS reader; it has a built-in blog editing tool with a drag-and-drop Flickr interface — i.e., drag a photo from your Flickr pool directly into a blog posting. For bloggers, this could be pretty neat.
• PubSub, Bob Wyman
  PubSub is another search-engine play, but it works in reverse. Most search engines are “retrospective,” meaning, they create an index of data and run queries against it at the time the query is submitted by the user. PubSub calls this “searching the past.” It’s an interesting distinction, and absolutely true; even in the best of cases, the newest data in Google’s index is a couple days old (in my experience).

  PubSub’s search is “prospective,” in that they maintain no index or archive. Rather, users write and save queries. There are no immediate results, in most cases, because there’s no index to search. Instead, PubSub monitors thousands of inbound links and performs matches in realtime. So, write a query today, and check back tomorrow for fresh results.

  The amazing thing about PubSub, the thing that merits a 3rd paragraph, is the processing speed of the system. They currently have about 700,000 saved queries, and they monitor millions of websites. For every new website update, they match it against the 700k saved queries. It comes out to over a trillion matches per day. And they run it on one dual-cpu Xeon box. That’s just astounding to me. They claim they can scale to 1.5M saved queries per box. Figure the typical user has 5 saved queries… that’s 300,000 users per box. Seems like cheap scaling to me.

  Update: In a followup conversation, Bob Wyman told me that the figure of “2-3 trillion” matches per box per day is actually an “effective” rate — there is some duplication in the query list. The number of unique matches per day is smaller.

  Most users, he said, save about 3 queries. “Their name, their blog…” I offered. “And their employer,” said Wyman. Me, me, and me.

  I pointed out that PubSub faces a nontrivial usability challenge, in that users submit a query and get 0 results. Whether it’s a superior experience in the future or not, in the moment it feels like a failure. Wyman acknowledged this and said they’re a switch-throw away from using their own retrospective search engine to show the most recent 32 matches. They have the data, but they’ve chosen not to show it.
