I wish I could find more of these, but ruby and python are indeed tiny compared to PHP: <a href="http://www.zacker.org/files/market_share_graph.jpg" rel="nofollow">http://www.zacker.org/files/market_share_graph.jpg</a><p>My judgement call is that the battle is over. I may be wrong, but I am on the right side of wrong. If I turn out to be wrong in the future, I'll look back and still think I made the right call given the data I had.<p>It has been a while since I decided to learn python and django. At the time I thought they would take over. Well, I was wrong. They have not - PHP has continued to grow faster than they have.<p>So this time my call is that PHP is the thing to stick to, particularly when I see moves like this one facebook has. In any case, this choice I made is the safe one. I can't lose by making this decision.
