I don't mean any offense when I say this, but #8 can be compared to an unrefined Internet Explorer icon and #23 is illegible and distracting. They also aren't very versatile which is an important aspect of a logo design. I wasn't going to mention anything, but those ended up being the two logos that received the most votes.

I understand this is for a token bounty on an online forum and one should expect varying degrees of quality. With that being said, I think there are some pretty promising designs that have been contributed. For example #1 by Dewi89. I also like the emblem/symbol part of entry #34 by mari4nn3. #14 by magalhanze has some good aspects and has been improved a lot since the initial post. And a couple more. These are a few examples of logo entries that can be scaled, stylized or applied with flat color, and still look effective when placed on various backgrounds or different mediums.

Just my two cents. I hope PoSToken ends up with a good one, cause their team managed to get some decent entries for a forum contest.
