MyProgs is a social bookmark manager dedicated to programs…ie. it is a space to keep a list of your programs, and organise them by tag (all tags, and users are public and shareable, making it a folksonomy).
You can combine tags in a search, and all exclude a tag by using the (-) sign…and every tag you browse shows related tags.
Also you can see all users who bookmarked a particular item
…this site is very similar in look and functionality to del.icio.us (aren’t most of them).
Future implementations will be to add more RSS feeds…at the moment there is a main feed, user feeds, but it lacks a user tag level feed, or even a general level tag feed.
Other intended features are exporting, ratings, tag bundles…
It seems these systems are all alike, but recently we are seeing folksonomies specializing in a topic (like this one is supposed to be used only to bookmark programs-as a place for people to share and discover programs, any other type of bookmark I guess would be considered noise or against the intention of this service).
Also, a specialised (topic/discipline based) social bookmark service probably makes it easier to gain a tight little user base…because it is specialised the tags seem to kind of have the upperhand on being more accurate.
That is, the tag “blog” on del.icio.us could refer to anything, but the tag “blog” on MyProgs is going to refer to blog software/program/addons.
