I often write about useful articles and interactives The Wall Street Journal publishes. Today, though, they featured four very useful resources that deserve their own individual post:

Ten Tips and Tricks Every iPhone and iPad User Should Know is a very helpful article. I’m adding it both to The Best Sites For Beginning iPhone Users Like Me and to The Best Resources For Beginning iPad Users.

Murder In America is just an amazing, and horrifying, interactive.

Iconic Electronics is a neat interactive of…iconic electronics over the years. I’m adding it to The Best Sites For Learning About The History Of Technology.

Eid al-Fitr Around the World is a slideshow. I’m adding it to The Best Sites To Teach & Learn About Ramadan.
