[lugm.org] Off topic : Lost Java Skills

[Avinash Meetoo]

Hi,

Java is not a *sexy* language. Yet, Java and C# are used by a majority of
programmers (some say > 90%) to create real software solving real problems
(think governments, banks, hospitals, military, etc.). These "professional"
programmers generally work from 9:00 to 16:00 then go home without ever
blogging on programming, asking something on stack overflow, etc. They are
essentially invisible yet form part of the large majority.

Geeks like us are in the minority and tend to favour the latest and coolest
things.

As for your question: Java (and C#) are used because, well, they work.
