it seems that a lot of beginners post threads about how such-and-such breaks in feisty. the last i heard, feisty is beta. therefore, i feel that only experienced users who are serious about *testing* or perhaps even *contributing* (i.e. - filing helpful bug reports), not "absolute beginners" who need a solid and dependable system, should be using feisty. in fact, if a beginner asked me which version he/she should pick, i would suggest dapper.
but dapper "just isn't cool" anymore.
either it is not clear to beginners that beta software is expected to have a few bugs, or these "beginners" are getting themselves in over their heads and then relying on the forum to bail them out.
personally, i think that too many new users have an unfounded need to download the latest (not necessarily greatest) software out there without a full understanding of the risks and responsibilities involved with beta testing.
i think an announcement, similar to Brunellus' warning about Beryl and Compiz (which is an entirely different, but not altogether unrelated, story) should be posted on this subject in the absolute beginner section.
sincerely, and with concern, daniel
