Eric Scheide of craigslist offered me a stream of consciousness summary of the craigslist database setup. At a conference last year, Craig showed a slide (which helped inspire my postings about asymmetric competition [1, 2, 3]) that listed the number of employees at the top ten web sites. Most of them have thousands of employees. Some have tens of thousands. Craigslist, at #7 on the list, has 19.
Eric's email has that embattled “news from the front” feel that you might expect from a site handling that much traffic with only 19 employees! [O'Reilly Radar]
