If you've ever done a search on Wikipedia.org, you know that as you read a particular article there are hundreds of links to related items that are incredibly hard not to click on. In my experience, I'll go into Wikipedia with a specific goal in mind only to find myself reading something completely different 20 minutes later. While this could be because of my desire to see it all, I'm pretty sure I'm not alone when I say some of the most interesting Wikipedia pages are the ones you stumble across you never would have known existed otherwise. Unfortunately, clicking around on links is not conducive to getting your originally planned research done.
Pathway, one of my old favorites that is incredibly useful for surfing Wikipedia, just got an update. Pathway offers a graphical structure for articles to make it easy to get back to your main subject once you've gone off course looking at some cool new item. Each node in the graphical network represents an article and the line between them represents the pathway you took to get there. Even better, if you don't have time to explore all of the offshoots from your original subject, you can save the graphical network so you can explore it later.
What do you think? Have you had a similar experience with Wikipedia? Is this just the program you were looking for or do you prefer to fly "fast and loose" on Wikipedia? Let me know in the comments!
