Some of them (clisp) are not functional. You can't read clisp in the logo because of the color choices. I looked at the logos first from a branding and functional perspective and my thought was that like all things there is tremendous variety in the set. Some logos were really good at doing the things you want to do with a brand. Others were metaphorically off-color. Others were really bad. Again, though, that's normal. Logos are, well, a balancing act between functionality, uniqueness, character, and polish.
