#9 - I like the layout of this design. The font and logo are a bit hard for me and the arrow seems a bit cliche. I am not always a fan of the blue and gray color scheme seeing that it is heavily used for blog logos. I would like to see a softer version of this logo with different color schemes (possibly a little red) and a redesigned "D" character.
#8 - Please see the comments for #9. I like the layout of #9 better with the character to the left of the font.
#28 - What a great interpretation! I love this logo and what you have done with it. If you have any other ideas like this one I would love to see them. Definitely in my top five!
Awesome work on your two newest submissions! All three of these are in my top five at this point. If you have any other ideas I would love to see them!
