interesting results, implied functionality, possibly evil functionality, possibly a way to avoid extremism in online networks, do I dare to eat a peach?

rather focussed on one social object, may have some ideas, anyone has used? similar to zotero

could be some good insights in here

clearly others are thinking about this in their domain, note the reference to ownership and posting references rather than content to the service (invisible to the user), taking things into one's personal stream (entanglement) and social graph based filtering

Using diigo's bookmark tool it hits me that if the system knows the tags ordinarily associated with a group are (by frequency of use even) you should be able to select a group by tag matching (so imagine the group drop down populating with the most likely choice and you just validate it, or if multiple groups match they are listed first (above the line) in alpha, with less likely starting again below the line in alpha order)

very nice, I especially like the reducing group list as the user selects tags that can simply be accepted if correct
the tag to group matching needs to be somewhat 'fuzzy' fit as I wouldn't want a group to disappear from the selection just because I added a novel tag.

Thank you Francois, excellent description.

I didn't follow the Common Tag saga, though from the outside it seems a standards effort by small players without the support of the major ones (delicious for example) which is pretty much doomed from the get go. I was impressed way back when when the founder of zigtag disclosed his cheap and dirty approach to semantics on tags with a wikipedia integration, a brilliant insight at the time, since much copied.

Zigtag suffers from a loss of its founder, it has not done anything of value since the funding parties pushed him out. It has also since lost its lead developer, because there is nothing interesting to do. The company has more or less disintegrated and the site continues on auto pilot. I had way too many issues with the tool not saving or sending and gave up as no one is at the wheel.

Ultimately I think re tag/group a group is just a tag with a few additional relations (member of, for one) and should actually be defined at run time rather than design time. Group is only one of the interesting combinations of relations that would be possible. Even what is referred to as 'tags' is not one thing. we have simple text, multi word text, defined text, tag hierarchies or rhizomes (meta tags if you will) and semantic structures all the way up to ontologies. So tag is not a simple thing even by itself. The simple named grouping function that is a basic text tag has many younger siblings.

In a world of real time feeds, repetition is an attractor

ping

repetition, reverb, you can set up 'remind me' or 'read later' with time options to have an item pop back into your 'real time' feed

ability to subscribe to a tag - perhaps a lower class form of group (bent's extensional vs intentional?) is automatically formed when >1 person sub'd to a tag

aside from the obvious feeding one group into another, the ability to specify two groups to be merged where the merge takes each post and tags it with the name of the group it was from

long sought after at twine, the ability to feed one group into another, and to create a group from a static saved search, or feed a dynamic saved search (rss feed of new results on that search) into a group

if posting to a group, multiple groups are possible in one posting, and clusters of groups can be defined, both as logical groupings and as equivalencies - those marked as equivalencies are mined by system for referrals and merges
