That's not why they are doing it. It's because it's better for everyone if things like browsers are essentially versionless, and everyone is on the newest version. Immediate automatic updates mean that users are always able to access the newest features.
That's an awfully subjective position to take. I don't have a problem with rapid release, but I have a problem with passing off minor revisions and bugfixes as major releases. And try to tell me the version doesn't matter when there's a regression or otherwise something broken on a newer rev that works fine on an older one. I don't know where this recent trend of "version numbers are evil" came from, but it's entirel…
On the dev side, you might refer to a particular code snapshot with a "version number" that might as well be 3.2 or r304 or "2011-08-3 12:03:47" or d1b119d8f117b16fcfa58b2be60df87a6c45ac58. Considering the nightmares caused by conservative IT groups enforcing version X of software Y for years, eliminating version numbers from the public for something as critical as a browser seems like a good move to me on security alone. For other things the formal major.minor.release-revision can still make sense. Personally I miss the "even minor version represents stable, odd unstable" pattern that's increasingly fallen out of use.
