Yeah, I have to add my voice to this viewpoint too.
I definitely have annoyances with Yosemite – GUI performance on a rMBP is lower, which is particularly noticeable during Mission Control use. I've also got the irritating slowdown/flickering menu bar bug that I've seen people report. But generally everything else has been pretty great.
I do wish Apple was more public about bug tracking – I'd love to see a public database of known bugs so we can track progress or something like that.
If anybody's interested in seeing some public information about known bugs, there's public user-driven "mirror" called Open Radar ( http://openradar.appspot.com ) that's really helpful. If you file a bug with Apple you can copy/paste the description (as well as any responses from Apple) there to help others
Unfortunately many bugs are not copied over there. I myself am guilty of not going through the hassle of mirroring every bug report I submit.
In the end, I believe it is more worthwhile to just file bugs [1] en-masse to have a "this issue is public" checkbox in their bug reporting interface. If enough people request this feature hopefully they will add it.
