Like other terms of service, Tumblr's is lengthy and includes paragraphs of dense legalese. However, unlike other sites' TOS, Tumblr follows up these thorny passages with easy to understand summaries.
For example, with regard to its eligibility guidelines, Tumblr's TOS states: "You have to be at least 13 years old to use Tumblr. We're serious: it's a hard rule, based on U.S. federal and state legislation, even if you're 12.9 years old. If you're younger than 13, don't use Tumblr. Ask your parents for an Xbox or try books."
Citing research from Which?, Keith Wagstaff of Time magazine pointed out that PayPal's TOS is longer than "Hamlet" and iTunes' is longer than "Macbeth." He asserted more sites should take their cue from Tumblr.
"If Hamlet can have Cliff Notes," Wagstaff wrote, "surely someone can write a summary of what I'm getting myself into when downloading the new version of iTunes."
