Yup! Release early, release often. Linux (kernel), Gnome, Ubuntu, Firefox, and Chrome (and lots more) are all on scheduled updates.
Edit: The advantage to rapid releases is that you can roll out minor updates when they're ready without having to wait for big ones, and you don't have to rush big ones for a deadline. If you miss one release, it's no a big deal because there's another one coming right up. Release when it's ready!
Yes, it is meaningless, and they intentionally hide the version number now - the download page doesn't even show it. But what could a major version number mean? GNU Emacs was on version 1.x for so long they dropped the leading "1." and promoted the minor version number to the major version. Ubuntu just numbers their releases after the date, e.g. 12.04 came out in April 2012.
Quote from Wikipedia that expresses my viewpoint on the subject:
> In principle [...] the major number is increased when there are significant jumps in functionality such as changing the framework which could cause incompatibility with interfacing systems, the minor number is incremented when only minor features or significant fixes have been added, and the revision number is incremented when minor bugs are fixed.
agree, these should be point releases I'd wager. However, they have to "keep up with the Joneses" (chrome, in this case) which has high numbered versions, I'm guessing...
The fact that you don't know what version you're on is intentional on both sides. Both Google and Mozilla realized that the version is meaningless and hid it.
