Here’s the deal. I’ve worked really hard in various ways to help push the Grails platform forward for the last 6 years or so. I absolutely love Grails and would not currently choose any other web framework to make web apps.
However it is completely unsustainable for me to work unpaid on this stuff, in fact I should have called this a year or two ago. Releasing plugins used in many peoples’ apps involves a high degree of responsibility, as well as ongoing support and maintenance.
Grails is brilliant because it works wonderfully for medium-sized websites as well as enterprise systems. It has nothing that restricts it to either of these markets.
