I haven't seen the new version of Blender, so the following comments are based on whatever version came before this one.
I am very quick at picking up software logic and GUIs, whether it's for CAD products or digital audio workstations or painter programs or what-have-you. I can usually open a piece of software and figure it out on my own. Granted, I need training to really be proficient at it, but I've yet to find a program that I open, try to make work, and simply cannot make sense of it without spending 3 hours watching video tutorials. Usually I unpack something and within a short period of time I know how to make things happen, even if they're simple things.
And then I met Blender.
When I first opened Blender, just looking at the GUI made me nauseous. I tried to make sense of it then quickly gave up because I had too much other software to learn at the time. That was a while ago-- I haven't seen the new interface-- but it was definitely one of the worst I'd ever seen, with the exception of the File Matrix. Good GUIs like Pro Tools, Photoshop, Corel, and 3DSMax have certain elements in common, one of the most important things being they don't dump everything in your face on the main screen. If you need a tool that isn't something you use at least every few minutes, it goes in a sub-menu that isn't difficult to locate, is in easy range of other similar tools, and has a dialog box for features related to that tool.
I'm not saying Blender doesn't have those things. I'm also not saying that professional software is perfect. But if a piece of software's interface layout instantly intimidates a user like myself before I've even clicked a single button, something is wrong.
This is a common problem with OS software or when you let engineers make a UI. As dialogs become more complex and toolbar after toolbar is layered into the GUI, developers become accustomed to the clutter and cease seeing it for its ugliness, much like having to smell your Indian co-worker's spiced curry brussel sprouts and broccoli lentil mix-- you just get used to it after a while. They then expect that users will also get used to it, and some of them do. But the rest walk into the room, make a funny face, go "phweew, who farted?" and leave, because who wants to smell that when they can just eat in the lunch room? Rajiv, if you're reading this, please, put that damn thing in an airtight container and toss it.
But I digress.
I will eventually have to learn to use Blender because I want to continue to do 3D modeling and I don't want to pay for a new program. I'm hoping that one day, Blender will be easier to for lay users to enter into. For now it just frightens me.
