"There's a wide gap between where ASP.NET's usefulness ends and where the really fancy stuff begins." -- yes. This is the frustration of ASP.NET programming _without_ the underlying HTML/JS/CSS/XML knowledge. It's like you can almost do everything you want, but not quite. The grid control, as you mention, does some totally sweet stuff right out of the box. But want subtotals? Time to learn about the IIS HTTP Pipeline.

It all boils down to what you are doing. Lots of shops can have 3 or 4 coders doing the mainline stuff and 1 guy who can do the tricky stuff. It's an effective use of lower-skilled programming resources.

I'd have to disagree with you on the libraries. While I'm sure there are some good libraries out there, when I'm plugged into VS I've got some kazillion or so things I can do without having to Google, link, recompile, or do squat. And I can easily make libraries to share with others. It depends on your needs. Since MS does a little bit of everything for everybody, the libraries are probably the broadest that are easily available.

Can you point me to someone that has beaten the libraries of the "Dark Side"? I'd like to check them out.

Java libraries, CPAN, and the Unix/C universe of libraries are three examples. But you should only check them out if there's a library that does the specific thing you want.

Yeah, I really have to second this one. It's not just the UNIX/C universe, though -- it's the UNIX scripting universe. As a particular example, how do you tie your graphing software to your analysis software to your screen scraping software? You could try writing them all in Python -- or you could just use pipes and tie together GNU plot and wget with some custom filters in Python. It takes a few years to get confident with this stuff; but once you are, you will never write so little code :)
