Might it be worthwhile to take the elected "superusers" on haskellers.com and let them police the skills list? It's become rather messy, with overly broad terms like "Mathematics" in it, as well as overly specific ones like "Other languages I know: C# .NET, XSLT, Microsoft SQL Server, XML, SQL, CSS, C, C++, Java, HTML, Visual Basic Script, Pascal, Rexx, Basic and assembler".
