So my tag thoughts lead me to fantasise tagging reality in some way. Could I use a GPS camphone to tag my environment? Find a nice restaurant, photograph and tag it there-and-then and it snaps into place on a useful, marked-up map of the City, complete with tags to aid retrieval. Other users could, of course, share my tags and places themselves could trigger a forest of tags as I pass (all on my heads-up display, I suppose).
In which I try, after 25 years of blogging, to drop my ironic stance a bit.
