After making some comments, I've been inspired to get some feedback on the PHP MVC framework PRADO. I've been using it for over a year now and I've very much enjoyed working with it, however I notice that throughout Stack Overflow, it doesn't seem to rate a mention when symfony or CakePHP are being talked about as potential candidates for a framework.
Is anybody using Stack Overflow using PRADO now? If so, how do you find it? Has anyone used it in the past but left it behind, and if so, why? Can anybody appraise its strengths and weaknesses against Cake or symfony?
