> When will we stop crying wolf for every tech company's demise when there's no enough data to support any kind of underlying trend?

I don't think it's tech companies in general that we're looking for the demise of. Social networks have been observed to have a short shelf life. Friendster had a meteoric rise and fall. MySpace had a meteoric rise and fall. Facebook has had a meteoric rise, and many people are waiting for their inevitable meteoric fall, and wondering who'll be next. Facebook seems to be intent on learning from history, hence their expensive acquisisitions of potential competitors.
