I went back through the thread and considered the different points of view. Yes, it's possible that Linux would be more popular with LESS choice. But, again, I don't see its lack of popularity as being a problem, and I certainly don't see the amount of choice in Linux as being a problem.
If some people stay away from Linux because they are bothered by the amount of choice, how are we to know that an equal number of people aren't attracted to Linux because of the amount of choice? We have no idea; but I certainly enjoy being able to choose between any number of distros, desktop environments, and applications that do similar things. To me, this is one of Linux' strengths, not a weakness.
mintnoob has pointed out that my attitude in all of this is kind of selfish, and I don't disagree with that. I came to Linux determined to make it work for me, and I accomplished that. I don't care about its popularity. My concern is that I'll be able to use it and never have to go back to the Windows world, or I'll never have to shell out big bucks for a Mac. Linux popularity won't be decreasing, as far as I can tell, so I figure it will be there for me.
In that sense, it's all about me.

But my point in describing my selfish attitude is that there are many other Linux users who feel exactly the same way.
If you want to make Linux more popular, I just hope it won't be at the expense of any of the choices that are available to me right now. Less choice in Linux would make it less appealing to me, and a lot of other folks share that sentiment.
In any case, Linux is what it is, and I'm satisfied with what it is. And I'm quite sure that it's only going to get better -- even with, as mintnoob calls it, "the insane amount of choice Linux offers."
