The Atlantic: "Something is wrong on Twitter. And people are noticing. Or, at least, the kind of people we hang around with on Twitter are noticing. And it's maybe not a very important demographic, this very weird and specific kind of user: audience-obsessed, curious, newsy. Twitter's earnings last quarter, after all, were an improvement on the period before, and it added 14 million new users for a total of 255 million. The thing is: Its users are less active than they once were. Twitter says these changes reflect a more streamlined experience, but we have a different theory: Twitter is entering its twilight."

The concept behind VoyURL is simple: A browser plugin records your every click, which you can then choose to share publicly in a real-time feed. Their website analyzes and shows you your online history in customized infographics, to identify patterns, recommend content and help you learn more about the way you use the internet. You can see the browsing history of all users in one giant timeline or follow a specific user. The service is currently in beta, but you can slip in here or here. [more inside]
The U.S. National Physical Activity Plan was released on May 12th, 2010. Similar plans are in place in several European countries (France, Switzerland, Sweden) and W. Australia. The Compendium of Physical Activities (older thread) categorizes energy expenditure levels of specific physical activities (yes, including sex, but I did not see that activity targeted in the US plan).
How are you feeling today? Are you energetic? Relaxed? Drunk? Maybe you're horny or lost in thought. Perhaps you're knitting, cooking, or doing some spring cleaning. Maybe you're simply untroubled. Whatever your mood, Stereomood will provide a soundtrack. (Warning: All links autoplay sound.) [more inside]
Hooping. The hoops adults use to dance and perform tricks are larger and heavier than the children's toy called the Hula Hoop. As hooping becomes more popular, people across the States and across the world are pushing the boundaries of dance and sport with a simple, easily made tool. Hooping for pleasure, exercise, and meditation is becoming a phenomenon. There's even a documentary. [more inside]
Sunspot activity is closely linked to climate. Although it observes an 11 and 22 year cycle, the overall trend of activity shows much longer term variations. The so-called Maunder Minimum (1645-1715) coincided with the Little Ice Age, while the Medieval Maximum coincided with the Medieval Warm Period. Analysis of beryllium isotopes from ice cores in Greenland shows that sunspot activity is currently at a 1000 year high. Could this account, at least in part, for global warming? Recent data from Mars suggests this may be so, while others remain sceptical. Bonus pix, more here.
