Thanks for the entries. #21 is better than #20 or #19 - however all three entries seem quite simple. I want something a little more sophisticated and eye-catching.
The entries that I'm currently ranking highly convey the concept of listening, and feel active.
Thanks for the entry #22 - it's better than the others you entered, but still not quite what I'm looking for. Reading through the comments on the leading entries may help if you're interested.
#39 is a nice concept, thanks. But I'm looking for something more distinctive. This design is a bit generic - with different words, it could be used for hundreds of websites.
#41 is slightly better, but still a bit too generic. And because it's generic I'd be concerned that people wouldn't recognise it as a logo, and would think that it was a search tool and try to click on it to search.
#42 is better again. It still doesn't have the quality I'm looking for. I'm not quite sure what's lacking but I think slightly less simplicity is what is needed. Perhaps more sophisticated icons, perhaps a more distinctive font (though I definitely want sans-serif), perhaps some gradient, perhaps a 3-D effect. Of course, don't do ALL of this - it will look awful - but one or two of these would help, I think.
