Safari Beta Web Logging (the Other Kind)

I noticed in viewing my Web logs -- the old kind, you know, the raw data describing a hit to your Web server with time, request, user agent, referer, etc. -- that Apple.com users are up to version 52 of Safari; the last beta release on 1-10-03 was 51. So I guess if you want to know how fast Safari's being revised, just look at the Apple.com hits from their gecko-like agent!
