I discovered this blog today and found it to be interesting enough to blog about. It's a link to a creativity blog off Mediapost. Everyone will tell you that media and creative are linked online more so than in any other format and I agree with that, but very few people will show examples. That blog shows examples!
Amy Corr writes the majority of the posts and she writes very well, so check it out!
And couple it with the reliable old AdFreak blog, when you want to find the funny creative/media ideas!
