Q) Do you think blogging is dead? No, I don't. However, the blog format needs a reboot.
For one, people don't have time to read as much as they used to. There's too much competing for our attention. This means you need to be creative to stand out. (This post is already longer and less visual than I would like it to be.)
Second, blogs must connect to social network hubs. Posterous lets me do so in a number of ways through auto-posting, but also by letting you send your comments into Facebook, Twitter, Backtype and Friendfeed.
