I've noticed an increasing number of Tweeters are getting around the 140 character limit by using links to graphics. I worry that this may raise Twitter's level of discourse above its usual bumpersticker simplicity, requiring that nuanced views actually be considered. I'm not sure today's political or educational climate will allow this.
So far the posters have as little depth as text posts, thank goodness. But they do look more profound.
Have a good week...
