C. MCGLEASON  SketchFighter is one of my favorite games. It appears like a simple action game on the surface, but there is a strong element of discovery and problem solving. It's whimsical, and I like whimsey, so that's another plus. And it is stable. Actually, rock-solid: it has never crashed on me, not even once, despite many, many hours of gameplay.

C. MCGLEASON  I've been using Camino as my primary browser since 2005. I started to use it not because I disliked FireFox or Safari, but because I was expressly looking for a different browser.

I manage a web software development department, and my general philosophy has been that everyone in my organization should use whatever browser they wish. That way, we won't get into the mindset of developing for just a few browsers. (By the way, this strategy has worked wonderfully - we support all modern web browsers very well, and the transitions to new browsers, and supporting new technologies like AJAX has been pain-free).

In any case, some folks in my shop were using FireFox, Safari, various IE flavors (on Windows), and Opera. At the time, I decided to go with Camino because no one else was using it.

I've been loving it ever since. It has a great, well thought out user interface, and it has that tried-and-true Gecko rendering engine. It also has Flash blocking capabilities, which I love, because I'm not a big fan of the "dancing shadow" or "hit the monkey" web advertisements.

It doesn't have the "plug-in feature" mentality of FireFox, but I can always fire up FF if I need some of those capabilities for work.

Camino is rock-solid. In fact, I don't remember the current version, 1.6, crashing on me even once. And I use it every day. I'm using it now, in fact.

I highly recommend Camino for anyone interested in an alternative to other excellent Mac browsers.
