From the webpage:
Sign up to receive a new dataset and fun problems every two weeks.
Improving your sense with data is as easy as trying our problems!
The first one is available now!
No endorsement (I haven’t seen the first problem or dataset) but this could be fun.
I will keep you updated on what shows up as datasets and problems.
PS: Not off to a great start because after signing up I get a pop-up window asking me to invite a friend. 🙁 If I had Dick Cheney’s email address I might but I don’t. If and when I am impressed by the datasets/problems, I will mention it here and maybe in email to a friend.
Social networks can be very useful but they also are distractions. I prefer to allow my friends to choose their own distractions.
