Hi! I really appreciate your entries. looking at entry #43 and #42 we have decided we wanted to stay away from the capital letter D and there is not much differentiation from distil and "it". Entry #46, #47 and #45 are much more appealing.
So far #46 would be our favorite but it is still missing a little something to show that it is filtering out bad traffic. It is a hard imagine to portray and we are having a hard time putting it into words but imagine a sieve (http://en.wikipedia.org/wiki/Sieve) but for web traffic.
Yes as my start with the contest, I'll update the logo tomorrow with better concept also. Sieve as filter I'll come up with a different approach tomorrow. Thank you.
