Google still leads the way in search, or does it? Its seems lately that other search engines are trying their level best to be innovative in their developments. Ask.com has had a major rebuild and promises to deliver faster results to certain queries. Data will be pulled from a variety of different online sources including question and answer sites like WikiAnswers.
The update is noteable if only by what this search engine is prepared to index. The engine is prepared to focus on content coming from individuals rather than professional publishers and personally I think this move has been coming for some time across the board too.
