That doesn't tell the real story though. Actual alternatives to these services do exist now and have some popularity. So some people do actually move. MySpace is an example of an eventual mass exodus. Anecdotal, but I personally know a handful of people who deleted their Facebook account and use other platforms instead. So it does happen. The question is whether or not it affects their advertising revenue in the long run. Zucks's solution so far seems to have been buying up the competition. It's not out of the question that one of these massively popular social networks will collapse in the next decade.
