There have been a range of “answer engines” or “help engines”
(Q&A sites) that have come and gone over the years. Some of them
might be considered “social search.”
Yahoo Answers, Ask.com (more recently focused on Q&A),
Answers.com, Askville (Amazon), ChaCha, Keen, JustAnswer/Pearl are among
those that remain and still exist. Verticals with Q&A angles are
also seeing success because of their more focused content.
Pearl, mentioned above, is a paid service that is reportedly doing
very well focused on professional advice. But most of the other Q&A
sites are struggling. Quora is a case-in-point, trying to broaden its
appeal as it searches for a business model. The just-launched Jelly is
also struggling for visibility but has considerable “runway.”
