One of the "outs" we give ourselves in social media is the complaint that so much is new, it's impossible to keep up.
Is it really? Is it social media that is moving fast, or is that just something we use to explain away why we can't give concrete results as quickly as others want.
It's a sop to our ego. It's an excuse. Social media is often referred to as common sense, but if that's the case, than what about common sense is changing so fast? For most of us, there's no difference in the real world between the speed of social media and the speed of any other discipline. From doctors to customer service to physicists, the pace of change has little to do with the companies that rise and fall, and much more to do with our recognition of what we've been avoiding for years.
Do yourself a favor and watch the whole thing, and keep it in mind the next time someone says, Social Media is moving too fast. They don't mean it. They mean, "we're going to be making some huge mistakes and our predictions could be way off, but don't blame us because we're cutting edge."
