Comment 63 for bug 267376

Please read https://wiki.ubuntu.com/TimeBasedReleases which discusses why Ubuntu schedules its releases this way and why it can't simply deviate from that at users' whim. The timeline is unfortunate but (with the exception of Dapper) completely predictable. http://tinyurl.com/4wpnan outlines all the objections noted here, and discusses specific answers to them.

Here's a hint: the timeline works and is a big reason a lot of people prefer Ubuntu to other distributions.
