"What You See Is What You Get". (for those of you who did not know that, well, now you do)
I always liked WYSIWIG interfaces because what I saw during creating/editing a document or an application was similar to the final output. So there were no surprises there.
On the other hand, I hated interfaces that were NOT WYSIWYG because they were unpredictable, deceiving, and annoying.
Now that the acronym is almost dead in computer land, I would like to revive it and use it in people's land. Again, I am very comfortable with WYSIWYG people even if they were far from perfect, but I am getting more and more intolerant to the NOT WYSIWYG individuals in my life.
