Yahoo Answers Social Search
Yahoo! Answers has now officially been released into main SERPs. Simply perform a search on Yahoo! and questions and answers are being surfaced within results in (from what I can tell) various formats - directly within the results and at the tail end of the SERPs. It is obvious that Yahoo is focusing on the social aspect in search (if you couldn't tell from its acquisition of del.icio.us). I have tested it before and was not terribly impressed with the quality of the answers to any of the questions and think that the system could potentially be ripe for abuse. The user and answer rating system will be helpful over time, but currently, answers to some of the questions just make my eyes glaze over. If you have a few minutes, it worth a look, if for no other reason that to determine the value for yourself - answers.yahoo.com.
