As the contest winds down, I always like to give a run down on my thought process.
First, I try to avoid cliches. They tend to make you blend in with other sites of your kind. You want to STAND out.
#91 | I love the power button cloud because it avoids many of the "social" cliches (People, speech bubbles) Yet still tells your story in a way that is unique and customized just for your users.
#86 | While giving a hint of cliche, it is still very unique in that the cloud idea is subtle but clean and unique.
#36 | is arguably my fave. It forms a cloud, but it does not scream cloud. It shows a group without using people (like the old MySpace logo did)
I feel all of these designs would help you stand out in a social media world that is cluttered with designs that often use the same elements. That is arguably the number one thing that your logo needs to do.
Thanks again,
Paul
