With @guga I would obviously talk about The Simpsons and let him plug his mobile game.
@sushi would tell me how his Monkey Island dutch translation is going forward.
And with you it would obviously be all about the cockney accent (because there are things you can´t teach me in the written form) and maybe we would recap the past X-Files season or talk about our favourite episodes or whatever…
No, sorry. In italian “to write a column” has a figurative meaning… it means to have a dedicated thematic corner inside a TV program, a radio broadcast, an internet site, and not only on a newspaper. I thought also in english it could work.
