I’ve noticed that I reuse very few tags … and thought I was just a poor tag-user. However, I read the other day a reference to a paper at the CSCW confernce last year; it reported that the average number of re-uses of a tag was just 1.31 . I thought this meant that most tags are never reused … I am not alone 🙂
Having downloaded and read the paper it turns out that this is the average number of users who use a tag – that is most tags are used by only one person, in fact individuals reuse their own tags a lot more … so I am no-good tagger after all 🙁
Incidentally, I use ultimate tag warrior plugin for wordpress and it seems OK. Only drawback is that if you want tags displayed with your post, they really get inserted into the post itself. This is not a problem for tags at the end, but would mess up an RSS feed if you like your tags above the post. I guess this is because wordpress does not have a handle for plugins to add things to display loops, so the only way to ensure the tags are displayed are to make them part of the post.
Also Nad sent me a link to a neat tag visualisation by Moritz Stefaner.
