"Of course, the saddest thing of all is that OmniWeb has pretty much vanished as a contender for the platform's major browser."
Agreed. I still use OmniWeb as my primary browser and have maybe two dozen custom search shortcuts defined - not just for Google and AltaVista, but for the the likes of the IMDB, dictionary.com, fedex, weather.com, the jargon file and Apple's movie trailers. That and cookie management are the two things that have me sticking with OW.
That and I have a long-standing history of rooting for underdogs.
