Gary Vaynerchuck just did a quick ustream talk in response to a comment he received via Twitter. The comment by @CreativeEmbassy said that companies are waiting for the tipping point before moving into Social Media. Gary's response was that it will be too late then. The time to get in is now, so that you can practice, make mistakes and learn from them. That way, when the tipping point does come, your brand will be ready.
