I guess we'll have to agree to disagree on how developers use documentation. I can't speak for others, but I don't use man pages unless I'm forced to. When I'm developing, I have about a dozen tabs open with the various documentation sources I need while I'm developing. I use online documentation *exclusively*. I do have a few things with documentation installed locally. Spring framework and the Java SE API docs being the two I use most frequently. But I usually do that because they're so big.
For everything else, I always, always, always use the resources available online. I do that because I switch back and forth between the official docs and googling for examples. I mix other sources in with official documentation. I can't do that if I'm locked into less on a terminal.
Sorry to burst your bubble, but I *really* hate man pages. I use them for finding out what options I need to pass to a program because it's been a while since I've used it and I don't quite remember. For that, they're really handy. I don't use them for anything else.

Having old versions of things on their website is an expectation I have. Maybe it's unrealistic. I can see no downside to having old versions of documentation hanging around for users of older versions of the software. If you put the version of your documentation in a position:fixed nav box somewhere on the page, you've addressed the problem of being half-way through a page of docs and forgetting what version you're looking at.
When you write the documentation, if you cover a new feature introduced in that version, you simply put a "since: 2.1.0" or something. If enough of these are sprinkled throughout, people get used to that easily and understand that this feature was introduced in version 2.1.0. The python docs are great examples of this.

I think that's reasonable, but I go back to agreeing to disagree on what format most developers prefer to use documentation in. Erlang folks I think are a little skewed because of the prominence of Emacs, info docs, and the really old school conventions that are perfectly functional but aren't taking advantage of new possibilities.

Uggh. X. Don't get me started on that! :)

Thank heavens! :)
XQuartz is awesome and everything I need in an X distro.

I do like this because it really burns me that I have to install X on server machines that will never have an X session run on them because it's a dependency.

I wish there were aptitude for Mac. If someone wants to really make Mac developers happy, they'd port apt to OS X and have a little GUI to download binaries, like you suggest.
Until such time I'll use Homebrew because it takes up less space on my harddrive and has fewer "parts" to keep track of.

I can't speak for anyone else, but having every possible option turned on by default is the reason I don't like macports. The fact that Homebrew does exactly what you've pointed out is why I like it! :)
