Abstract:

Here at SitePoint, we have started thinking about HTML 5, and whether or not the time is right to publish a book about it. To help us decide, we asked a number of web luminaries what they thought. Their answers were both varied and interesting. Take a look and decide for yourself: is it time you started learning about HTML 5?
