Just found this Lifehacker post which I thought was worth sharing.
By numbers alone, there are more people that regularly sign into Facebook than Twitter + Myspace + YouTube combined. While we are all aware of the importance of Facebook as a way of engaging with our audience (Sorry, but I HATE the word “Fan”!), few seem to really know how to make the best of it. This guide looks at how Facebook works, and most importantly, the steps to make Facebook work for musicians & record labels.
Well worth a read.
