Depending on the kind of business and website visitors the TLD designation may not matter in some cases. Trying to see what others have experienced with different businesses; whether it be b2b or b2c.
Agree with other responses. You may compare Ruby (considering Ruby as your reference) with Python. There are good discussion on Ruby vs Python in HN. One of the threads is at http://news.ycombinator.com/item?id=682101
