We're beginning a fairly large effort to share the vast number of protocols accumulated in our lab and pushing them all to the cloud. Naturally, you don't want the knowledge of older graduate students lost when they graduate.
We have had experience with putting all of this information into OpenWetWare but there is a small but non-trivial learning curve with the wiki-format. Another possibility would be to create living documents with google docs and organize the links in a wiki format. Finally, there is always the dropbox method of having a bunch of files in folders. I was curious about good methods to create a repository of protocols.
