Answer: Their lips are moving
The Telegraph is running a great series of columns on startups in europe, edited by the ever controversial but never dull Milo Yiannopoulos (@Nero on twitter)
The piece on the 20th January was provocatively titled Are European start ups lazy? which got some predictably annoyed reactions from hard working startups in europe.
The underlying question is valid though - why is Silicon Valley better at producing startups than Europe? I'm fortunately to have spent time working for a US company based in Silicon Valley - and made many friends there who have or are working in startups. My overall impression? Silicon Valley is better than europe because of the density, and the competitiveness of startup culture.
