Blogs and Wikis - Differences

I see a couple of differences with blogs and wikis. I see blogs as more conversational and more of an alert time of system. Wikis I see more as a database or resource that is meant to be up to date but not necessarily changing on a daily basis. Blogs are better for commentary or alerts. I've created a blog (not released to medical staff yet) (LSUHSC-S Medical Library Evidence Alert) for my library to keep physicians and others up to date on evidence based guidelines, reports and reviews. I had done this before the class started but I've learned some tricks that I'm going to incorporate into the blog since I only knew the very basics.

I could see wikis being used to create interactive educational tools for new residents. Not only do they have the stress of functioning as physicians with more autonomy but they often have to learn complex procedural tasks for the institution (how do you write orders etc, what abbreviations you are NOT supposed to use etc.) Students currently have big paper manuals that they don't carry and rely on others to educate them which can lead to misinformation or bad habits through students. A wiki might be a good tool that would work and could be updated by multiple individuals.
