No, no the potato is the topic of @gertu her CCC contest.

@felixgarciap has poem or lyric about "carrot"
@olivia08 a photo about flowers
@team-ccc has "what does CCC means to you"
@freedomshift has "what does today mean to you"
@marblely has my favourite... (Look for the theme I forgot) and I host "Looking back look forward" with a theme too.
So 7 people host a CCC contest, all different.
