As an interesting side effect of adopting Technorati tags, I have rethought the use of blog categories for Get Real -- which were starting to get out of hand, anyway.

Basically, because of the specificity offered by tags -- which are potentially infinite and perhaps time-limited in their use -- I have decreased the number of categories at Get Real from like 40 to around 20. I have dropped some categories altogether, etither collapsing them into others (like "Geolocation" and "Proximity" which are now "Geolocation, Proximity"), or replacing them with their corresponding tag.

I guess what I would like is a finer-grained control on the domain of tags, really, and then I would just drop categories altogether. I'd like to be able to represent that a tag is intended to be used locally, which would be the equivalent of a category. My blog platform could scan the entries for this information, and create the equivalent of category archives. But remote platforms, like Technorati, could also scan this information, and take advantage of these category-like tags in some fashion.

[A side note: One hazard of this housecleaning is that you can make a dumb mistake. I did. I unintentionally deleted "Social Networking" as a category, and had to manually recategorize 50-something entries.]
