What about other .Net languages ?

We are all gathering around C# and Vb.Net in this community, but what about other languages ?

I would like to know more from developers who embrace Cobol.Net, Fortran.Net, Forth.Net, Eiffel.Net.

Interesting to know which application they can develop and also their experience on .Net. Maybe it's a marketing stunt from Microsoft but I don't really believe it.

Some links I found:

• Eiffel free editor
• NetCobol for .Net 2.0
• Cobol .Net forum (embedded in a C# site ;-))
• ASP.NET/COBOL.NET Database Access Example
• Delta Forth.Net
• Salford Fortran for .Net

UPDATE:
Yes I forgot other languages like ADA, Perl, Prolog, S#, SmallTalk, Python, etc... !
The etc is there because the list is long. If you want to know more Christophe Lauer mention this page with a comprehensive links collection.

And another list here send by James Steele 

But to go back to the point of this post, who use these languages ?
Apart one blog I know about Python (not sure it's .Net either), where are the Forth.Net bloggers ;-)
