Wikipedia is a a huge database of information one can take advantage of to learn about any topic. In fact, there are so many articles available in on Wikipedia that one might never get to read them all in a life time or two. You can always browse through Wikipedia content using your web browser. WikiNodes for iPad takes it to a whole new level. It gives you a whole new way to go through content on that site.
Wikinodes is not your average Wiki browser. It displays articles in form of nodes. You can go through nodes easily and interact with them. The nodes are linked together, allowing you to put the dots together faster. This tool is quite visual, saving you time finding what you are looking for.
WikiNodes for iPad has a superb GUI and is quite promising. It clearly demonstrates how our web browsers could look like in the future. It is very useful tool for research too (especially with its nodes and links instructions).
