I like your logos but i'm not sure that people know that it's a social network when they see it. And i know it's cherry but if people don't know they can't imagine cherry when they see the logo :/
The cherry's stems point connecting each other can symbolize the social network, and the 2 overlapped circles ( cherries ) symbolize 2 people adhering to that social network ( represented through stems ).
I've designed the logo in this way with this in mind: simple, modern and elegant.
