So what is human powered search anyway? PART 1

There is a lot of talk about "human powered search" these days. Since co-founding ChaCha, which is lumped into this formative category, I have come to find that human powered search means many things to many people.

These meanings include human edited web pages, message board-style services like Yahoo! Answers where anyone can answer any question (and often-times the person
answering is doing so more for the entertainment value of their "answer" than anything), and true expert services where questions are asked on specific topics and people who are knowledgeable on those specific topics respond with answers. is not human powered search
One thing that really needs to be cleared up is the notion that (formerly somehow utilizes people who provide answers. It is tough to tell exactly what Ask Jeeves had in mind when it first launched since IAC offers only a brief company overview. definitely does not fit in the human powered search category today.

Hand-written and human edited content
Many services exist today that utilize people to write web pages on specific topics. These are considered part of the human powered search category. is the best known service utilizing this approach. I would include Wikipedia in this group as well. Mahalo is another recently launched service that follows this basic approach to creating web content framed in a search context. Valuable content can be created by people writing and editing web pages and this content is attractive to Google. The SEO power afforded to such human-edited sites is the primary value equation that allows them to create a niche on the web. It will never be the case that human written topical web pages positioned as search sites will change the way people access information. They definitely do not make a big impact where access to information and answers is soon to matter most - on mobile devices. Also, quality and validity of the information on Wikipedia is being called into question so frequently that it is banned by many universities as a valid information source.

Message boards
Message boards have been around since the dawn of the web. Today some message boards are oriented toward people asking questions for others to answer. These are included in the human powered search category. Examples include Yahoo! Answers and the now defunct Google Answers. Yahoo! Answers has tapped into the massive traffic of Yahoo! to gain a large base of users (90M or so). Anyone can answer questions on Yahoo! Answers once they great a login.

Paid expert services
There are also services that require users to pay for access to specific experts. These services are proving that users are willing to pay a premium for efficient access to experts online that can answer complex questions accurately.
