I don't think that Brainfuck a very usefull and easy language is. I think C# is as easy as VB.net but you will have to think on some extra's like ";" on the end of a line... (I prefer to use VB.net)

I rather like C# then Phyton because the Visual C# editor gives you more structure than phyton does (in my opinion). (The drag and drop function to make a form is also very easy if you are new to programming.) I also have started with small basic and C# looked a bit the same as small basic, . And maybe rather VB.net, it looks like C# but is less strict (and easier to understand). But the only thing that a child want, is to have fun with it, so let it stay enjoyable. Try to make a sort of game, a cool-looking app, ... (Every child want to learn as long as it is pleasant.) (I also don't think that a console isn't good to begin, it isn't cool to program, a visual thing is nicer for kids than a stupid black box with a lot of text in it.) Greets, Wim, 17
