Some more comments from a designer's point of view...
It is important to differentiate between "fundamental" and "superficial" concerns. Both matter, but for this next vote, focus on the fundamentals. For example, postpone discussion about kerning, and what not. Colors, kerning, and so on can easily be changed, and all three designers would be happy to make minor changes. Instead, here are some vague fundamental questions to consider.
1) Which logo evokes the overall feel you want for SpamAssassin?
2) Can the logo work in multiple media? For example, on a web site, on a 1- or 2-color T-shirt? How about multiple sizes?
3) Which logo is the most self evident? the most memorable? the most timeless?
4) Will the logo satisfy the Apache Foundation's needs for continuity?
5) Which logo will best represent SpamAssassin among the general public and the developer community?
6) Which logo do you instinctively like the most?
7) Which logo do you want to see in the next article in the New York Times, Wall Street Journal, or MSNBC? :)
