We’ve got to give kudos to Jaroslav Tulach for his excellent book on designing APIs in a Web 2.0 world.These days a lot of companies are jumping on the API bandwagon without really knowing why they need an API or wht makes an API effective. Obviously, you can find a lot of information on different APIs on the net. But the theory is hard to find, so the gap was there in the market for a good book about API design patterns. But thankfully, Practical API Design has been released for those of you interested in starting up your own APIs. No more excuses for badly designed APIs.
