The aim of ChatScan's application will be immediately obvious to anyone who has ever bumbled from empty chat room to empty chat room, hoping that someone interesting will strike up a conversation. Not only will ChatScan send you to active discussions, but its proprietary interface makes it easy to flip from one chat to the next without having to download multiple chat clients.

"If it facilitates people having more meaningful conversations, it could add to chat as a medium," notes Amy Bruckman, an assistant professor at the College of Computing at Georgia Institute of Technology, who has done extensive research into online communities. "There will be less of a chance of running into a 'Hi, how old are you?' conversation, and [a greater possibility of] finding more meaningful conversations instead."

Besides helping you find like-minded hobbyists and enthusiasts (or, I'm guessing, willing cybersex partners), there are also a legion of other, less obvious uses for ChatScan. There's the obvious vanity search -- "Who's talking about me right now?" And it should also be easy for the FBI, for example, to peruse chat groups to find out who's talking about building bombs or who's on the prowl for nudie pictures of teenage girls -- assuming, of course, that anyone involved in such illegal activities would be stupid enough to do it in a public chat room.

But ChatScan could also exacerbate some of the nastier aspects of these online communities. A dirty old man, for example, will find that it's easier to search for a chat room of giggling teenage girls. And Bruckman notes that ChatScan would make it easier to stalk or harass someone who frequents chat rooms -- an occurrence she says isn't unusual. When all chat rooms across the Web are searchable, "your ability to get away is severely diminished," says Bruckman.

Segal asserts that he is actively concerned about privacy issues -- "Privacy right now is a pretty open nerve," he contends -- and as a result ChatScan won't search private chat rooms, rooms with passwords, or one-on-one chats. But there are other open communities that might not cozy up to the notion that their chatter is suddenly searchable. Many public channels on UnderNet, for example, are habituated by a core group of regulars who consider their cozy (albeit public) chat rooms a community. If lurkers can flit in and out of conversations, following keywords rather than relationships, will this hinder the bonds of that community?

"There's a certain sense of intimacy that develops among people who feel like they have a community; this technology is making it easier for other people to join their group, which they may or may not want," explains Bruckman. "Even for a public group, it's like a tavern -- you may have regulars that hang out at a particular tavern, and there's a sense of intimacy. With this, it's like the tavern is running national advertising."

To enable its service, eNow will be tracking and archiving millions of hours of chat. Will every word you type in a chat box be permanently stored in a database? That would require an amazing amount of data storage -- and eNow wouldn't say if such a vast chat collection is in the works. But any archiving of chats might alarm those who like to think that their digital chatter merely disappears into the ether.

Still, privacy advocates aren't, for the moment, terribly concerned about ChatScan's ramifications. Andrew Shen, a policy analyst at the Electronic Privacy Information Center, points out that a product like ChatScan is "a double-edged sword -- it allows you to talk to other people but it also allows you to be spied upon." But he says he is reluctant to think about it as a privacy issue -- after all, chat rooms are public even if users choose to think of them as intimate forums. He notes, "It may chill some free-flowing discussion that may go on in chat rooms, and make me more reluctant knowing that people can listen in virtually. But I'm hesitant to call it a privacy concern."

ENow is aware of the concerns that its technology might spur -- but Segal doesn't consider the privacy issues a barrier. "I'm sure there are dangerous aspects in everything to do with progress," he says. And, in turn, he says he wants to "stand back and ask what we're facilitating and make sure it's moving forward and evolving rather than being abused. It's a great responsibility."

In other words, eNow doesn't just want to build software, it wants also to build ideas. So Segal is starting a think tank to foster those ideas: Along with eNow.com, Segal is developing a partner site, eNow.org, with Kevin Kelly, Wired editor-at-large and noted futurist.

Under Kelly's supervision, eNow.org will study the social implications of eNow.com's software. Through its Web site and a series of grants and events, eNow.org will invite pundits, futurists, entrepreneurs and enthusiasts to discuss the Net's "global collective consciousness" -- a collective consciousness, the idea goes, that can be viewed by perusing the thousands or millions of simultaneous real-time chats using ChatScan.

"I started the foundation because I felt that the Net is biology, not technology," Segal says. (Kelly could not be reached for comment.) The foundation will discuss how access to real-time information changes the way we see the world around us; does it turn our knowledge sets into extended relationship networks rather than acquired information databases? "Access to information is changing the consciousness of people and how they perceive the world around them -- the insight they have isn't all acquired knowledge, but is external knowledge," Segal ponders.

Of course, it could be said that chat -- a world of one-liners, abbreviations and truncated conversations -- may not be the most effective medium to study the world's interactions and ponder their meanings. ENow is going to give it a shot anyway, and Segal hopes eventually to extend its search technology into other kinds of live entertainment as well -- making live television searchable, for example. In Segal's vision, the entire ephemeral "now" will soon be logged for posterity, as long as it's in digital form. Starting in April, you might just think twice before you type.
