Patateo is going to be a fun website in France, with funny videos, funny content (top list, animated gifs), etc... just like a BuzzFeed, DamnLOL, etc...
Patateo doesn't really mean something, but it's very close to potato/potatoes... there might something around it.
A Patate in French (= potato ) is someone silly, and part of many expressions.
If you want to play with it, I have added as attachment a few potatoes comics/graphics I bought from graphicriver a couple of weeks ago for this logo. This is only for ideas, inspirations or if you have an idea with it. I don't want to see all logo with the same potato.
The idea/concept of potato is just for inspiration/example only... if you find something better, do not hesitate to let explore your creativity.
