We like your concept. It's as if it tells a story. It's ok if you explore other, more colorful options too. Don't feel like you're held to fitting into our existing color scheme. We are open to new ideas.
The only criticism is that the logo itself seems a bit dark and heavy, but we really like the idea.
We like the globe's depth and brightness in #7, but the gradient over the text in #6 and #7 doesn't work. I guess it's ok to have flat text.
You are very creative. We never saw the word "Go" between the two words. I wouldn't mind working that into the overall design, but I think we like what you've done with the separate globe, better.
Orange, purple, and that teal color are VERY popular right now, but I think we'd prefer colors closer to the primaries.
