I try to keep up - really! But oh my oh my there's so much to learn when you are an illustrator or designer or anybody using digital graphics technology. The training never ends. Right now, I'm working on my (formerly paltry) Photoshop skills over at Lynda.com. For 25$ a month, you can learn Photoshop, Illustrator and many other software programs at your own pace.
Here are some other links I'm adding to my digital graphics rolodex to help keep up with all the new advances. Adobe Illustrator CS3 has thrown a few new curves into the routine lately, but they are some pretty exciting changes. Creative Techs, a computer support firm out of Seattle has 3 pdf booklets on their site for free download that give an overview of "What's New" in CS3. Also, check out the quicktips section of their site or subscribe to their newsletter.
Last year I discovered Mordy Golding's blog when I encountered a bug in Illustrator CS2 and his work-around tip saved me a lot of crashes. For me, his Real World Illustrator blog will forever be THE place to visit for info on Adobe Illustrator. It's time to get the CS3 edition of his book too, Real World Illustrator.
Finally, I found another link that might be helpful to add to your digital graphics rolodex. This article by James Dempsey for MacWorld lists a bunch of links that can help you beef up your font collection. He offers a wide array of links to sites that offer free fonts and sites that sell commercial fonts. Roll on!
