I run a website that is a simple tool for a certain task. Right now it is available in english only. It attracts half a million visitors a month. It's mainly word of mouth, press and social traffic. Since it's a tool, there is no text content. So I only rank for very few keywords in search engines. Do you think I should translate the page in all languages? It contains only few words, so it would be easy. I could have a french version at fr.mysite.com, a portuguese version at pt.mysite.com etc etc. Have you made good experiences with this?
What do you think, why Microsoft will produce their own tablet? Because they think the other hardware manufacturers will not support windows or because they think the other manufacturers will not produce a good tablet? Or because they think the hardware itself will be the profitmaker?
