It would be great to be able to add an item to your OPML outline via a bookmarklet
eg. a bookmarklet for one of your outlines in OPML Workstation.
I’d like to be able to click the bookmarklet to add the URL of the page I’m on (HTML link, RSS feed, OPML URL) to a section in one of my outlines, or even just add some text in a box.
If del.icio.us had an OPML URL for every user, then this could be the answer. It wouldn’t be a usual outliner, but del.icio.us could be an outline that has a 1st level folder with items that are links or feeds, although most people bookmark normal HTML links…I wonder if it could also offer an outline tree view.
Anyway, if a del.icio.us user tag had an OPML URL, you could call this tag “Reading List”, and bookmark feeds within this tag. This tag would be a Reading List and people could subscribe to its URL in an RSS Reader, any changes you make would automatically be reflected in who ever subscribes to it.
So whenever you come across a feed you like, hit the del.icio.us bookmarklet, and save it in the “Reading List” tag.
RSSor would be most suitable for this type of thing, as it is a focused folksonomy for feeds (and an RSS Reader as well), if only each tag had an OPML URL, or at the account level.
Feedmarker is an RSS Reader that has an OPML for every feed tag, Rojo could do the same, ie. an OPML URL for every tag you organise your feeds in…this way when you hit the bookmarklet to add a feed you are adding it to the Reading List at the same time.
