Although I voted for #1, I do like aspects of others.
I'd like to take this time and run through some of the nice and bad things that I find about each logo:
#1: I love the compactness of this logo, and yet it still has quite a bit of information. The colors really appeal to me. My only gripe is the elliptical (exponential decay) shading/greying. I think it detracts from the logo. However, if it was left just the way it is on the first 3 letters "CAN", and not used on the rest, that would have been pimp'in! Like I said before, there is horrible text that is hidden in the white part that really catches my eye. I *assume* that the text would be left out of the final version. If not, YUCK!
#2: This was nice because it incorporated fun florida themes, such as boating, palm trees, and aircraft. It's just....... the headphones............... I don't know, they seem too big and distracting. It's very big too.
#3: is really nice, what with the cd player/cd and the headphones with wave between them. I like the colors too. My only complaint there is the elliptical grey mask over the bottom half....... its so big and the angle just doesn't *do it* for me. I really would have had a hard time considering between #3 and #1 had #3 not used this effect.
#4: This is nice because it incorporates florida into the design. Sadly though, I don't really draw a J from it, and so the logo as a whole isn't instantly apparent. The arm is a little creepy to boot.

The "by author" text doesn't add anything to me, and only takes away from the simplicity of the logo.
#5: Ed, wonderfuly done. All the info is there, and it has nice fit and finish (to a degree I would never achieve). Only thing that I'm not crazy for is the size. With all the detail, it needs to be big to be readable. I have no idea how the logo is going to be used........ whether if it's going to be a badge, or a banner, or whatnot... but for cases where a small logo is needed, this would be tough.
#6: I like the florida theme. The palm trees are horribly pixelated though (a big detractor), and I'm not sure if this was intended or just............ was it copied from somewhere? That's the impression I get from it. The tiny headphones over the background are also a little out of place when I look at it. Text is a cool font though!
#7: I like the text for this, except the elliptical shading/greying. It really distracts me. The headphones were an interesting concept, but they turned out looking like 2 mice. Also, the headphones are effecting the color of the text, which for me might not have been the best choice. Cool general concept though.
#8: I liked both of his entries, though the orange'ish red one was perhaps my preference. Technically they are very nice, but they are lacking information on the meet. Plus, I really hate the Latin (?). I don't know, but trying to read it really ticks me off. Now had that been in english, this would have been a serious contender for me.
Yup, so that's what I thought. Take no offense to my negative aspects of your logo.... only try and learn what you can from them, or just ignore me ^_^.
