I’ve never quite figured out why anyone would want to use Twitter. Twitter is a “microblog” where you post short, very frequent updates Why would you want the whole world to know that you’re just about to go bike riding, or eat supper, or go to bed? It all seems a bit narcissistic to me.

However, someone (presumably at NASA) has adopted the persona of the Mars Phoenix rover currently on the surface of Mars, and is twittering regular updates “from the planet,” as it were. Each post has a snippet of information, or a link to pictures, or something of interest.

Overall it’s a pretty cool way to get the average person involved minute by minute with this latest space mission. Kudos to NASA for their originality.
