Wiki's!

From book reviews and previews to how to's. Rhyming not intended, wiki's can provide you with tons of information, (again) at your fingertips.
Let's face it, information overload is not an uncommon complaint now a days. Websites try to give you everything they can because our attention spans only give them an average of 20 seconds. Enter a wiki. Quick, simple, and often (important this) accurate information with none of the desperate clutter of full run websites.
I like to think of them as bare bones web pages, where a bit of information at a time makes a difference. You can see where it all began and get the joke. (sometimes) It can give you ideas on how to start pages, or how Not to finish them, and it doesn't have to be only you! Whole groups can collaborate on wiki's and if something is not accurate, there are experts out there that can help you set it straight.
Collaboration is the key. It's not locked down, instead it's open to all. Not only you learn about a topic, but so do your work mates, roommates, and class mates. Friends, family and coworkers can all get involved in wikis.
Drag your library to the fun! They can create book reviews and previews. Program times and ideas. Feedback on how to improve a program. Online bookclub?
I know there are more ideas. I'm just overloaded!
