Thanks very much for the feedback.
Firstly, I don't have any problem with not sitting in number 1 - I'll be happy when the design hits the nail on the head.
Yes, type is cooking nicely now.
#76 - yes it's a step in the right direction. I'm still thinking about that one so I might be able to offer another development.
#74 - funny, this is the first atom, or orbiting style logo I've ever done - so it was quite fun to compose it. Yes, it is vibrant and alive but maybe, as you say, too "sciency". Still a great balanced design though.
#79 - okay, what this design means to me - it represents pieces coming together to form a whole, like information and skill coming together to create something which, like most well-designed things, makes people say "wow, why didn't I think of that?". Like most great ideas and inventions, products and processes - a lot of work goes into them but the outcome doesn't seem to be a sum of the time, work and energy put in. This logo reflects that process - simple mathematical shapes in what seems like a rather simple composition. But the shapes stand for all the elements of your business and products, coming together. Hope that makes some sort of sense!
Ok, the main thing though, is that the logo gives you that gut-feeling that it's right. Whichever one you go for make sure it feels right for your team.
I'll keep tweaking and there might be another idea before the end of the contest.
But thanks for putting your thoughts into words. And you're not being difficult whatsoever I assure you :)
