There is an interesting service called Gollum Browser which is a pretty good frontend interface to view Wikipedia pages. It is more like a online help with minimial clutters and usage of AJAX to speed up the loading time. The interface is quite usable – give it a try if you are often using wikipedia!
Gollum is the name of my newest crime of invention. By reducing the complexity of information, I have created a fast and eyefriendly browser through the free encyclopedia “Wikipedia”. Originally this invention was built up for my daughter but now I have expanded it to the world for free as an open source project under GPL.
