It's the Headline, Stupid!
And I'm talking to myself on that one.
In this attention economy, when the headline of my blog posts are syndicated via twitterfeed, to Twitter and then on to FB, Skype, and Plaxo, the key is to have a good headline (and now I've added FriendFeed to the mix)
If you are an RSS reader person, you know this already. You read the headline and immediately decide to read more or move on.
Even more evidence of the 7 second rule (that is, it's the amount of time you have before someone decides they aren't paying attention to you).
