There are some who still ride the fence about social media. They don't "get it" but they want to be "in it" – so they open accounts, say something once and sit the fence. They don't try to find a task, engage in a conversation or even do something ballsy (Mistakes are Tuition). And then, they blame social media.
If your task is listening to what others are saying, that's great! But for the love of Scoble – don't say that and then say you don't subscribe to any RSS feeds or search strings.
Things change (improve?) fast. If you stand in the middle and do nothing, the door will knock you on your apathy.
