Wonder Why to use a Wiki??

Cool, came across this on my LATI journey..Why use a Wiki?

#17 PB Wikis

I think that there is a little bit more to wikis than what we did in the Sandbox, although it was fun. I believe there's more to the learning curve than say, creating a post in your blog. Knowing a bit about HTML would help. I did create a log-in and a new entry and then linked to my blog. I can see how things could get lost very easily, like the front page, if a new page wasn't created first.
