NewHoo calls itself a self-regulating republic where experts can collect their recommendations, without including noise and misinformation. NewHoo's directory is small compared with Yahoo, but NewHoo generally contains links to higher quality sites. Its creators hope to eventually have a web catalog that is much larger and more comprehensive than Yahoo's. That kind of size might be an asset, but for now, I think its relative smallness is the asset. If you think a category isn't up to snuff, you can make yourself an editor and make it a little better.
Categories can have multiple editors.
Some choose to devote many hours to honing their categories while others just tweak their category during the occasional a spare moment. NewHoo is both a great concept and a well-implemented one. Of the many questions that I've asked Ask Jeeves, this is one of the very few that it couldn't provide a good answer for. But for many other sorts of questions, Ask Jeeves is a fine tool that can help deliver the answers. It helps to think of Ask Jeeves as more of a research tool than traditional search engine.
