I have mixed feelings about Yahoo!'s new plan to charge for search results via their API. On one hand, I am a fan and admirer of Carol Bartz, and her efforts to turn the financial fortunes of the company around are certainly evident here. And, there is value to the service for sure. Then again, does this mean the end of mashups? Many developers, the API target for sure, think INFORMATION WANTS TO BE FREE (as in speech, not beer)! So, what will be the effect of this move. Let's wait and see. I think it will probably be changed within the year, but there's nothing wrong with experimenting with new models.
