Thanks for the submission and it sounds like your product offering is very robust!
#18 - I like the two row format of your design. I would love to see "Sales Strategy" all on the second row. I tend to shy away from the blue and gray color scheme because I feel it is over used in the blog world. I feel the bar graph image is a bit cliche but would love to see something else in its place that is a play on the "D".
#17 - I like the idea of the S and the mountain reference but the result is not what I am looking for. I would love to see some additional ideas. Please focus on designs with a white background as that is how the logo will be displayed on the blog. I tend to shy away from the blue and gray color scheme because I feel it is over used in the blog world.
#11 - Please see the comments for #17. As with #17 I do not like the "S" logo but would be interested in additional ideas you have.
