I whipped up some for everyone to use. Went light on the text because Facebook hates text with images, and tried to convey the community aspect of steemit, but the real selling point for this platform are the rewards.
If you feel like using one of these, please put 50% percent of the bounty back into the ad campaign.
Looking forward to seeing what the community comes up with!
Cool, thanks!
