Blogs and wikis and so on...

All of this is most confusing. I am not sure what to put in the blog and what to put on a wiki. I suppose that a wiki is in effect for a group to get together and add and delete photos, prose etc from a common source whereas a blog is just for one person to talk. I think there are things I put on my wiki http://friendsphotos.wikispaces.com which should be on this blog. For example the songs, the things about the region and so on. I will start using this space for that from now on, well....
