A few months back I went to a KMRC event in Hong Kong atteneded by a cross section of government agencies, NGOs and private companies. Most of the attendees had taken the time to prepare a brief presentation on what sort of KM activities they were doing. It was really interesting that many groups confused blogs and wikis. Being able to post to a shared location was understood to be both a blog and a wiki. Also, most everyone thought a wiki had to be wide open to everyone in the organisation.
Just for my record, a blog is for me a place where a person or a small group of people who speak as a group, keep a rolling diary of views, events, how-to, links and so on. A blog is a public diary.
Just for my record, a wiki is a shared collaboration site. It can be shared among a large group or a very small group. The Wikipedia is the ultimate example of collaborative site shared among a large group. However, many wikis are just for a few people to collaborate on a project, event or process.
The difference is significant. A wiki is about group collaboration. A blog is about sharing knowledge.
Take a look at Stewart Mader’s Future Changes blog for excellent resources on wiki development.
