gcal2excel – a handy little web app that lets you export Google calendars into spreadsheets.
Tiny URL – turns those long, yucky URLs into neat little 20-some character nuggets. Yay!
Coursera – fantastic courses on a wide variety of topics, both creative and technical.
w3schools – where I go to jog my html memory.
Lynda.com – of course, there’s Lynda.com — my all-time favorite site for brushing up on all my design apps. I sign up for months at a time and then suspend my subscription during busy times.
