Facebook's rude shock over data

The big tech companies thought they were unstoppable, says Merryn Somerset Webb. They may have cause to think again.

Over the last few years, you will have heard a lot about how the strength of the "network effect" means that Facebook can't fail. So many people use it to socialise, to organise events, to make work contacts and to get their news that its long-term dominance of all of our social and a large part of our working lives simply isn't in doubt. We haven't been 100% convinced by this (see endless editor's letters past) and this week we are less convinced than ever. Why? Because the value of the networking effect depends on a critical mass of people staying with the platform in question andthat depends on them continuing to trust theplatform.

This week, they don't trust the platform.Thanks to new data abuse revelations, the fourth top trending topic on Twitter on Tuesday was #deletefacebook. The share price is down 7%. Mark Zuckerberg is several billion dollars poorer and anyone who was fool enough to still think that the big tech companies are an unstoppable force (for good or bad) has had a bit of a shock.
