TC,
I actually agree that there's nothing wrong with discussing Linux here (apparently we're managing quite nicely in this thread

), but coming here with a positive opinion about Linux is much like going to Slashdot with a positive opinion about Windows. Which I think is kind of sad, because there are people on both sites (and many others), that are into computing because of what they can do with computers, not only in terms of what they can do with computers, but also in terms of how they can personalize their computers to suit their own needs and aesthetics.
I've seen themes here (and on other sites for Linux) that have enough effect on the system as to render it substantially different from the base material, both in appearance and interaction. In my opinion, anyone who has the attitude that they can improve their user experience on a computer, regardless of the underlying OS, should be exactly the kind of user that is willing to honestly examine the different offerings available, if only because they might find something they like that can be translated to the system they prefer to use.
Just as an example, I like Macs, but I don't own one, largely because of cost, and also because I'm not willing to absorb the cost of transferring all of my apps, etc. But I do think that there are things that the Mac does better than any other system, and if the preponderance of Mac like themes on this site (and others) is any indication, I'm not alone in that assessment. Additionally, I feel that there are things that Windows does better than anything else, and there are things that Linux does better.
I like computers. I like all kinds of computers, and I've been playing with them in one fashion or another for 27 years. I have successfully managed to avoid being infected with the idealogical malady of believing that any one system is fundamentally better than any other. For me, all computers (and operating systems, etc.) are a limitless resource containing knowledge and fascination and discovery. And the more you know about all computer systems, the better you'll be able to understand and make use of any particular computer system.
