Delphi is very similar to VB although it might be more cross-platform independent than VB ever will be (not that hard to do). As for knowing languages...you can know a ton of shite about a language and still learn something from a total n00b. In JRoc's defense (n00bish's post), almost everything he listed could be done on command-line in unix/linux. Then again I could be wrong.

As for me, I know a little, hehe...
