Talking with folks, my impression of social media  – all of it – blogging, podcasting, video, twitter, ning, Facebook – it’s all an experiment right now.

Social media impact is hard to measure – like, say, reputation management. But as @unmarketing says, “How do you ROI or measure your other business relationships?”

Right now, a social media experiment for a company would cost about $20K. But in 18 months to 2 years, it will likely cost 10x that. Get in now. Experiment. Fail. Try again.
