You can ask your friends that worked on Illustra about that and the other
horror stories on http://philip.greenspun.com/wtr/illustra-tips
These days, of course, pretty much everything, content-wise, is stored in a
database. Slashdot and gra.ph uses MySQL. Most big e-commercial sites use
Oracle or MSSQL.

I don't think application servers really solve anything for web apps. It
just becomes another layer of complexity that has to be understood,
documented and maintained by already overworked programmers. Essentially,
your business logic is dictated by your data model and the forms you
provide to represent the valid transactions.

I'm a big KISS advocate. Orly knows relational design. Orly knows Perl and
DBI. Let Orly design the basic data model and code the logic in Perl/DBI
for Apache. Then I can steal his datamodel and code the logic in Tcl. You
could steal the datamodel and write JSPs for it. Someone else could code it
in PHP or Python, etc.
I'd say we'd get a lot more done than if Orly had to hunker down to learn
Java, JSP, JavaBeans, JavaFoo, JavaBar, etc. to write a relatively simple
form generator.

I'm smarter than average. Therefore, average, to me, seems kind of stupid.
People weren't purposely being stupid. It just came naturally.
