Here’s a thought for you: Part of the endurance of Unix is that it does the core things well (System Stability, running processes etc) but that it makes combining functions easy (where would we be without scripting as glue , the ‘|’ operator and the ability to tail the last 500 lines of output from a process then grep the results?)
The more you think about it, the more Web 2.0 is heading the same way. You have big, stable processes like the Google Maps API , RSS feeds and other XML interfaces to-from your favourite website and tagging services from Del.icio.us to name but a few (or even your own Enterprise Apps written in Java). You have scripting glue (be it PHP, Ruby or even Perl) to tie them all together. What you get is mashups able to quickly evolve new services, but with serious industrial strength underpinnings to cope when your site appears on Slashdot.
What are your best examples of Web 2.0 as a Unix box?
