I respect the current one.
I do prefer the old one, but the current one is still regonizable as a fox around a globe representing the word wide web ball.
I think from 2013 is my favorite. I'd probably like the fox from 04 and the globe from 13 the best.
17 and 19 are both cool logos on their own, but are literally duller then the others. They got rid of all the pointy bits. The fire gradients on both are nicely done.
I honestly like 2004 the best. I could see the issue with it then when resolutions were lower, but I feel like we could go back to it now. It looks so much nicer, though arguably less recognizable at a glance from across the room or something.
im torn between old design and new frankly. I really like the little details present in the old logo, but not the explicit 3d nature of them. I much prefer the flat styling of modern applications, it's just more suited to functionality IMO.
Bring the modern one some more detail, give it a paw, make the globe blue, i'll be happy.
