Thank you for your entries. Nice choice of color and font. I like how you utilized my slogan in the logo. I like #15 better than #16. While I like a thin outline, the thicker outline makes me think more of cellular division pictures than a Venn Diagram. Perfect circles are more what I am envisioning, although making them look like thought bubbles was a clever idea.
I like the side by side format. I like #37 better than #24. I like the thin outline on #38, but the lighter color of #37 is better. Thanks for your revisions.
The dual colored slogan of #91 isn't my thing, but I like the font choice of #89. The bigger lettering of #89 and #90 is better than the tinier letters of #79.
