.NET =D HAHAHAHAHAHA....
Ya know, these are the same people that decide that using the canned security in .NET and windoze is perfectly acceptable. But I guess some people have to learn the hard way. By the way, don't get the idea I've let this keep me from learning a little of it myself.
As for Perl in the "enterprise" (I never saw that part of Star Trek), I still agree with chromatics question. As for the definition, why isn't it simple? His was.
As for reading other peoples code and working in large groups, I would be willing to make a cheap bet. There is no project so big that you need so many programmers. I honestly believe many projects are over-engineered and the programmers under skilled.
I have never had the opportunity to work in large groups. However, that has never kept me working on large projects. Here are the reasons that I think (I could be wrong ;) there are very few differences between languages when it comes to big problems.
If you think about it, a language can only make these things worse by resisting the need of being intuitive. Skill, simplicity, documentation, and communication are all failing points of not only programming projects, but also businesses.
