I've been doing VB
on and off for the last 2-3 years, I think it's a great language, a good balance between language power and simplicity/user friendlyness.
I would like to learn how to use it in more detail, one thing I wouldn't mind making is a HTML editor that can be used over a network to provide real-time updating. So that multiple developers could work on the same script at once.
But I'd say go for it, VBs a great language to learn.
