1 in 5 tweets contains a URL
I love Twist. It's designed to show trends in Twitter. But I use it to spot patterns. And these graphs show that the %age of tweets that contain 'http' (ie a URL) is just over 20%.
What's more, tweets are more likely to have links on weekdays than weekends. And tweets at 10am are the most likely to contain links. (Mouse over the graph to see times).

NB These charts are dynamic, so if you're looking at this in a couple of years' time maybe they'll show something different ... And the graphs show things at your local time (so they are showing me 10am in the UK as the peaks). If a person in USAÂ tweets at 4pm (USA time) and a UK person at 11 pm (UK time), these both happen at the same time. A UK person looking at the graph would see both shown at 11 pm.
It was Twist that I used to show that more retweeting goes on at 4pm in my post showing that 4.01pm is the best time to twitter.
