Tim O’Reilly notes in Update: Firefox vs. IE in OReilly Network Logs, “as of last month, Firefox passed IE, with 46% of all access to OReilly sites, vs IEs 45%.” Now, one percent is not significant, and the cause can likely be explained in a number of ways; perhaps there are more popular FOSS books than new Vista books in the past few months. But it is great to see that competition continues to prod Microsoft to compete, and inspires Mozilla to achieve.
