That's not really a productive criticism. Are there any specific issues you've had with Grails? Have you looked at it lately? It actually has a fairly thriving developer community. Admittedly, the community is mostly Spring/Java stack exiles, but its starting to attract quite a bit of new developers and PHP/Rails converts as well.

POS? You must be joking. Not looking to start a framework/platform war, but Grails is on par with or better than: Ruby on Rails, Django, <insert your favourite web platform here>
