"TL;DR: Don’t depend on Delicious; host your own, pay for it elsewhere, or hope for the best. Use real-time feeds to stitch the bookmarking diaspora back together into topical aggregate indexes." When both Les Orchard and Jeremy Keith are saying something similar, I listen.

Phil Gyford follows up on my automated copying of machine tags from digital photo EXIF by suggesting some versions for photographs for film.

"There is also the question of when and why a tag evolves in to being a first class data type and whether that’s actually reflected in how people use tags. Dates are one example, and geotags another. Each are uniquely indexed in the Flickr database and, still, people continue to add both as tags on their photos. The short answer, of course, is that it’s usually just easier to type 2008 or 2009 than to try and remember a specialized syntax for doing searches."

A nice way of displaying machine tags, including reclaiming HTML tables (and with a nod to the Flickr machine tag browser; thanks). I'm not sure if I could make this work for the Flickr version; there are possibly too many namespaces. Still, maybe I'll try for the most popular ones.

"I don’t really care what this means for folksonomy and the rest of Web 2.0 - tags work for me on Delicious." As they do for me on Flickr. I think that's probably the biggest point I'd make about them if I ever did make a long form post: my tags work for me. Anything else is a bonus.

Damnit, I need to think about this and respond properly (just like deusx did to the piece I was originally referring to). Some unrefined thoughts: Flickr's search is as good for non-tags as tags; tags are for personal use, and as such can be terribly handy; tag clouds can be more useful than heirarchies [todo: tag cloud UI for machine tag browser?]; Flickr are starting to do useful aggregation (eg placesForTag, tagsForPlace, as used by wherewhatwhen).

An interesting, somewhat long, survey into tagging, and how much it contributes over titles and descriptions. "How come the same person who tags his photo {Milan, Italy} is able to title it Galleria Vittorio Emanuele II?" The answer to this, I suspect, is that uploaders encourage batch tags but not batch titling. Also, as I noticed in where? what? when?, top tags for places tend to be geographic, but not terribly specific. I'd love to see a well-thought-out riposte, mind.

Tom Gidden does some of the things I want to do. I need to have a look at this code.

Not for the main review (it's not an app I'd use anyway and the one-thing-per-note limitation is dumb) but the bit on tagging. He's right; space delimited tagging is horribly Unix-y, and wrong to boot.

Hear hear. 1001 and Flickr Export both manage to make typing in tags a chore.

Well, he got another one.

Some good links delving further into the Heim hyperspace papers. Well done for avoiding the lazy option of just propagating the Scotsman sci-tech story!

I wonder what happens to the existing links I've used for: on

Now, *this* is more interesting than mattb's first delicious experiment (to me, anyway). Looks like my use of tags and extended titles is a bit... odd.
