5 years since development ground to a halt.
Pity really, it was hijacked by a group of people with 'certain ideas' of how everything must be, and no willingness to compromise with the general user base.[...]Compare it with Blender, [..] a continuous flow of real and useful new features
I'm actually happy that the Gimp is resilient to changes just for the sake of changes. I does what it has to do and it does it very well. It has great support for various file formats. Never crashes. Can do all kind of neat tricks and if it can't you can write or download a filter to do it.
And best of all: it doesn't bother me to learn `new improved` interface. The Gimp of 2015 is about the same as 10 years ago, with only minor conservative changes - for better or for worse - to the user interface. While i partly agree that save/export should have been combined in same menu, it's also a very minor inconvenience and actually a good habit to save your work before you export to some format that looses information.
So, if you are happy with an alternative, sure. Not everybody willing to pull a thousand $ for software and a mac. I - and many others - are very happy with Gimp just as it is and regard it as a properly maintained project. It requires some learning to unlock all abilities and know all tricks, but that's with all feature rich software.
