I started pushing links to followers shortly after I started blogging. First there was the Frontier News page, then that migrated to the home page of scripting.com, then we came up with RSS, and aggregators, and made the jump to Twitter and Facebook.
All along I've been aware that there's an art to this. There are chances to insert humor and mystery into the flow. Why did he point to that? And you could comment. I put short little one or two-word phrases after posts, sometimes even in a different voice, all meant to provoke a response inside the reader. A personal one, different for each reader.
Anyway, as Twitter and Facebook turn more to news, and hopefully at some point other news orgs will invest in their own infrastructure for this, let's think about how to better develop this art. Some way to discuss it. If you do this, do a blog post with your ideas.
