Kikora logo changed (for the worse)

In 2007 I designed the logo (but not the website or application) for the Norwegian startup company Kikora. The company makes software for math teaching to pupils and students. The logo I created was using the idea that the solution for good math teaching is "equal to" Kikora, hence: =kikora. The colors chosen where supposed to show that they were a serious company. I also made a color scheme that had more vivid colors too, but it was turned down. (See the whole designmanual here.) This is my design: 1.








Two years later they got it redesigned by Miksmaster. They have done wonders with the website and the application as Kikora didnt use any designer on it before. BUT, and I know I am biased here, how did this redesign make the logo better?!
