I would be more likely to study a language that has a sensible name, has a web site that doesn't hurt your eyes and has a manual that isn't "One of the worst manuals I've ever seen in my life", http://c2.com/cgi/wiki$?GooLanguage.
It's not worse than Arc in that regard. Goo broke a lot of conventions, yes, but if you know your way around Dylan, Self, and Scheme, you will get Goo fairly easily.
