#21 - I really like it, Genesis! I'd like to see the design concept with a few alternate fonts styles and colors if possible. Can the name wrap all the way around the logo or is that a stretch?
#20 - The green brings out the blue in the mini-globes a bit more so I'm partial to it.
I think the green is the strongest, Genesis. None of the others really beat it out.
I haven't really seen a font that I like yet, though #28 is nice. Not sure what it is but they seem out of place with the logo, perhaps a little too simple. What do you think?
