"Mr. Chen added “There are a lot of services trying to solve the information discovery problem, and no one has got it right yet.”" <br />
"“I signed up in 2005 and I didn’t use it again until 2011,” Mr. Chen said with an embarrassed laugh." <br />
"Some of the early users are still fiercely protective of the service. Mr. Chen and Mr. Hurley said they planned to invite the earliest users to test a version of the new site and solicit feedback about the designs and features." 

"They begin to see another world, a world where the Web is social and interconnected, where we all benefit from the trails of data created by one another's everyday use of the Web. That's just the beginning."

"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."

Hmm. "of all the viral loops that Facebook benefits from, its Photos app might have the largest viral loop of all built into it. Whenever one of your friends tags a photo with your name, you get an email. This single feature turns a solitary chore [into] a powerful form of communication" Personally, I can't imagine using FB, but I can see why this would work (especially as most people, oddly, like photos of other people, as opposed to, say, skyscrapers or trains). (The number of people using Photobucket scares me too.)

$29 utility for Mac OS X for easily setting tags on files, photos and the like. Uses Spotlight. Might be nicer than the iPhoto interface (did it get any better in the new version?)

"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.

"Use it to collect and share bookmarks, notes, videos and other content. Twine organizes your content, learns as you use it and recommends new things to check out."

Ooh, what's this in one of the scripts? «event KAnewkey» given name:the_keyword? Of course that's in AppleScript, but maybe I can get access to raw AEs from Ruby and do it there too. If not there's backticks. (edit) damnit, uses Keyword Assistant. Sigh

Text "track subject" to Twitter and you'll get messages from anyone (public?) mentioning subject. Nice, but why's it SMS only? And what if you wanted to start a message "track"? I bet people mistwitter commands, too.

Something to think about for groupr- I already have an outstanding sort-of-request to show new photos only in a subset of groups. I'm not interested in making group posting easier though. Hm.

Noting the new tag limits.

last.fm and tags. Hmm. I kept meaning to put taglike data into my genre tags, but the collection is too large
