He may not like compiz, but really who cares? If i recall correctly, Phoronix also has had an article or two dissing Gnome3 too.
I for one, use Compiz (0.9.8/bzr) and like it quite a bit. (which you would probably already know).
While Kwin is very good, i wouldn't want to KDE (too much bloat). Gnome-Shell also is not my cup of tea (too rigid, ugly). Compiz is lite, can be used standalone, or with another DE. It works with my (Wacom) tablet *significantly better* than any of the alternatives, in large part due to it's plugins and CCSM and the granular control it provides.
I see bugs getting fixed all the time, including those that i report (some i hadn't reported, that on update disappeared). I've seen improvements visually, such as at one point compiz becoming smoother (on Nvidia), or more recently your reworking of the menus/shadows ~ which seems to be better. I've also seen reduced resource consumption too. One prime example of that would be that compiz (0.8.x through 0.9.6) used more CPU when idling and/or when using blur, this isn't the case for me anymore. building compiz from source is MUCH better than even 3/4 weeks ago ~ i was able to ditch most of my build script, and replace it with just a few lines ~ being as only one branch is needed, and the build system (now) allows everything to be built at once. ~ which i personally really like
I could think of a lot more examples, but i think what my point is that some of us do like/use compiz, we can see the project improving and value the work that goes into it, even if someone like Michael doesn't.
I think especially in the last few months, there has been lots to be happy about concerning the direction of Compiz.
