We launched http://www.adsvise.com to help designers & marketers get through the mental maze of digital ad specs. It would be great to hear what channels you think we should be adding and what tools you would like to see next.
This is a really cool tool, very helpful. Thanks for sharing and its bookmarked! What about Yahoo ads?
This was a huge problem for us. With all the cheat sheets, infographics etc it's not really so easy. That's why we created the site. As Andrew says, feedback would be great
