It's difficult to pick a new language to learn. Let's face it, everybody is enthousiastic about something : I've got ruby-fanatics friends ; some advise me C# ; others would recommand Lisp, to see something completely different. And so on. There are too many reason to pick a particular language. So I figure : perhaps there are much less reason to avoid a particular language, and it will make my choice easier.
Asking directly to every members of stack overflow the question could be spotted as "too personal", so I'd better ask for a book or a link.
Do you know anything that lists the "weak spot" of most well-known languages ? It's easy to find arguments like "Learn the X language, 'coz it's good for doing this, and that", but much more difficult to find the "You should know that the Y language is not good for graphical tweaks / complex computing / small script / etc.".
