Maybe there's a correlation to the fact that I'm not a big Twitter fan and the fact that never in my life have I used wall. And that, on the other hand, find / | grep is always right at my fingertips.

From 'sfearthquakes' on Twitter: By Marc Hedlund

One of my favorite business model suggestions for entrepreneurs is, find an old UNIX command that hasn't yet been implemented on the web, and fix that. talk and finger became ICQ, LISTSERV became Yahoo! Groups, ls became (the original) Yahoo!, find and grep became Google, rn became Bloglines, pine became Gmail, mount is becoming S3, and bash is becoming Yahoo! Pipes. I didn't get until tonight that Twitter is wall for the web. I love that.
