Soon you may not need to squint at distorted letters to prove your humanity.

Sanjay Sehgal thinks the average CAPTCHA, that collection of deformed characters that Web sites ask users to type out when registering for an account, is both too easy and too demanding. The image tests designed to weed out spam-spewing bots often annoy real people--and rarely keep out determined spammers.

What's this?

Who's leading the conversation?

This visualization below allows you to see the impact that each user has on the current conversation. The top row contains the group of users who have had the most impact, the 2nd row the group of users who have had the 2nd most impact (et cetera). Users with similar impact are grouped together, and the average score of the group is shown to the left of the group. The author of the article is also shown on the left, in their corresponding group. Each user's score is based on the number of comments the user has made plus the number of votes their comments have received. The scores are calculated relative one another, so while their absolute value is not particularly important, their relative difference does indicate a larger difference in impact on the conversation.

The company Sehgal founded a year ago, Pramana, takes a different approach. Instead of submitting users to a test, the Atlanta-based company's technology plugs into Web sites and invisibly analyzes users' online behavior to determine who's a human and who's a bot. "We don't demand that users prove they're human," Sehgal says. "We simply watch them and decide for ourselves." (See "Robots In Disguise.")

I am very keen on not having to squint at those stupid things that I so often get wrong, but I am also nervous about them tracking my net habits. Even seeing what items my mouse hovers over on the page can give a lot of info that I would prefer is private.
