Why Wiki? Great question!
I probably will not do it justice, but here are some quick thoughts on why wiki
Wiki is a technology that allows members (likely after an approval process) the ability to alter/change/enhance a web page quickly and easily (an immediately). It is often used in collaborative projects to help aggregate information.
When is wiki really useful?
-When key information needs to be regularly updated
-When key information is held by a diffuse group of people.
-When maintaining/updating all the information is too big a job for one person/group, but is a manageable job if spread out across the membership.
Just to give one recent example, consider the threads on metal vs. plastic stents.
I am not sure if the updated website will have information on metal vs. plastic stents, but there was a ton of great info in the recent thread. Within a day I could have turned that information into a "metal vs. plastic" stents wiki page. Within a week there would probably be enough comments / changes so that the "metal vs. plastic stents" page would likely be one of the best sources on the web for real life experiences and information on this issue. As time passed, the page could be further enhanced with experiences and paper references, etc.
I am not sure how frequently the website gets updated, but I would not be surprised if it occurred every 1-3 years. So the difference I see is that a wiki would allow world class information to be user-created in days, whereas a process that relies on traditional web updates may take years (and likely stent information does not even make the cut)
As a second example, consider clinical trials. I could imagine a wiki page that lists the 10-15 clinical trials that have CC patients participating. I think it would be great if we could get those members to give updates as to how things are going on a particular trial. It is maddening how little information is available, and how frequently clinical trial experiences and results never make it into the literature. With a wiki, members would have an organized place to record and compare their experiences with others.
I could go on, but I think the key thing is that we have lots of members with important information. However, it is difficult for those members to incrementally add to the knowledge base their key piece of information. People are busy, and people dealing with CC are often really busy. If it is not easy to contribute your piece, the information is often lost.
A wiki makes capturing and organizing all the little bits of information much easier and efficient.
My intuition is that it would be a huge boon to our members, and I am hoping to figure out a way to make it happen.
