Robin Good's insight:
zResearch is a curated, collaborative next-generation search engine, allowing great customization and filtering of results, clustering and auto-categorization, some truly stunning alternative data visualization options, and the ability to collaboratively curated and organize search results into multi-level collections.
Once you are registered inside zResearch you can start immediately to curate your own "search spaces" in which you can save both any relevant results as well as any web page you run into on the web, by using the dedicated bookmarklet.
Within a search space you can create as many folders as you like and multiple search sapces can be joined into "groups".
zResearch offers two alternative ways to visualize results in visual clusters. One is a treemap-like display and the other is a circular diagram which make it very easy to see at a glance the forest(s) from the trees. Navigating among such different forests is extremely fast and easy and doesn't require a reload of the page.
zResearch offers also the opportunity to invite other individuals to collaborate and contribute to a specific "search space" or "group", to make a search space private, or public, accessible by anyone and even embeddable elsewhere.
In this fashion subject matter experts, trainers and guides can set up and maintain specific custom re-search spaces that can be used by anyone out there.
zResearch offers also "alerts", which can monitor specific topics and keywords for you, and can search across texts, images, video, educational materials, books, products, the deep web and custom repositories.
My comment: zResearch, brainchild of an already effective curated search engine named SearchTeam, is a truly effective, easy-to-use and useful search engine, which puts the re-searcher in fully in the drivers seat.
The set of categorization, editing and search curation features is from my viewpoint very good and using zResearch to create a reference search space for other people interested in a topic is extremely valuable.
I highly recommend zResearch to anyone interested in following, monitoring and maintaining an effective reference catalog of categorized info on any topic.
Free to use for 30-days after registration.
