I have come across the BOSS project in YDN and was wondering how this is less popular than Google Custom Search(which can be atmost as flexible as BOSS I think). I look at the pricing chart and there is the answer. If I have a website, with a traffic of say less than 1000 queries a day, I still have to go through the hassle of paying the $1 bill once a year? Yahoo could simply multiply its developer-users by 100s of times by simply offering a free edition for low traffic sites. May be if 100x guys try it out 3x guys may want to go for the commercial edition. Today we have cloud services which have free editions but Yahoo still wants to go the dinosaur way. Amen to that.
