When I bookmark my blog posts in del.icio.us I sometimes use a lot of tags, but only 1 or 2 really grasp the aboutness of the post…I use several others as there may be chunks in the post that also refers to closely related stuff.
In library land I remember this issue being overcome by being able to search via two types of subject fields: Major Descriptor - overall aboutness of the item
Minor Descriptor - the item also covers this stuff, but isn’t totally about it
…this would be a great implementation in del.icio.us as you could have 2 versions of the same tag.
Maybe I can get around this by prefixing my tags
Eg. the tag “Technorati”
MD:Technorati - when the bookmark is actually about Technorati
md:Technorati - when the bookmark mentions a bit about Technorati, but the overall aboutness of the item is about something else
…and if the bookmark has only a passing comment about Technorati, maybe we’ll just leave that to the full-text engine to find.
