I have been using NOF since the early days. Granted, I'm not a prolific web site creator and it certainly isn't my main mode of income. But I have to say that even in my limited use of the product, I've finally had it. I'm tired of working around the work arounds. I just converted a friend of mine's web site from NOF 12 to Joomla 1.7. It was relatively quick and painless. The product is open source and therefore free. There are tons of extensions that far exceed anything NOF has to offer.
I'm sorry NOF but in today's market, you just aren't cutting it. If this is the result of your outsourcing your development than I would say it's a major FAIL.
