I like the shadow of # 6, but the alignment of # 10. Would like to see the "Internet Marketing and Consulting" incorporated more into the design. I'm also a little concerned people won't realize the 5 is actually a 5. The word "five" may need to be included.
The spacing between the words in #102 definitely works better. (I was reading "FIVER" for some entries.) It will also help readability for applications when the entire logo is printed in one color, or revesed against a black/dark background.
#220 This design will work well on a colored background, as well as small sizes, one color, etc. It is versatile, and I believe would be quite memorable and recognizable as a brand image.
