I read the post yesterday and it has a point, Mark is not what he used to be, Facebook is not doing big things like Google and Apple. Now his company is public Mark is only looking for making profit
When you say 'big things', I assume you mean things like Google Glasses, Google Driverless Car (does that have a name yet), etc. etc.
Google has always taken these sorts of initiatives, it is a huge part of their corporate structure.
I'm not familiar with these sorts of initiatives or 'big things' at Apple. Can you elaborate?
Microsoft does big things in research, but I don't believe they match the pace of Google, though that could just be perception.
Not every company needs to be doing 'big things'. I suspect we would have said facebook never really did. They just executed brilliantly on a few key not very innovative things, like the news feed, like button, universal sign-in, etc. None of these are big things, but they are what made the company what it is.
