From the Semantic Web mailing list:
Every time I work on logos, I learn something new! The main
lesson so far from the Semantic Web logos: Get more feedback on usage policy before deploying. Thank you all for your comments. Most of them related to the usage policy, so you will find a proposal for a new one below.
As the W3C discovered, kids love empty boxes. Of course, the example of logo morphing pointed out in the mailing list was the most innocuous and plus speak of the bunch, so we’ll have to see how far we can really push this ‘box’ in the future.
