Interesting, I am building a filter for twitter, and one of the things I want to filter OUT are actually pictures, especially instagram. Other offenders are tweets without links, tweets full of hashtags, or vanity retweets. I'd love to have statistics about what different people use twitter for, especially those who read HN, for me it's a way to get realtime news.
