Loved this talk from Gary Vaynerchuk. His intensity is something to behold - and he makes some great points. One that really stuck out was using all the different platforms we have access to in the right way. Instead of just whacking links on twitter (something I'm guilty of) use it to connect with people on twitter.
Don't just use these platforms to link people to content that lives elsewhere.
Create content that's native to that platform, or don't bother.
