See my reviews of other Mind Mapping / Modeling services below-below.

The dynamic model beneath has limits, but is, I think, both very neat and very useful, once you make sense of how to use it. My guide, plus my assessment of its limits, are below.

• • At the bottom you can choose between 3 viewing modes – I recommend Circle. Don’t click ‘Begin’! It will take you to the login page and you won’t be able to return to our page.
  • On the left, gray-backed words are tags. Clicking a tag will make that ‘tag’ the centre of the [universe], with everything else organized around it.
  • Circled dots represent bookmarks – clicking on them doesn’t do a lot – it makes that bookmark prominent on the right, and if you choose you can then click on the red link inside the bookmark, or you can click on one of the orange tags inside the bookmark.
  • Words in double-edged frames with white backgrounds are tag bundles (tags associated with each other, according to the bookmarks’ creator (in this case, Jonathon)).
  • Green lines appear if there is a connection between bookmarks, beyond the fact that they are both/all in the current tag. If you click the dot and see the bookmark’s tags, you will find they share other tags.
• This approach has limits – I can’t arrange things manually the way I would want them to appear to you, or to me. I can’t define what tags should appear when you first view the collection. And I don’t think there’s a way to search for keywords! (We should be able to search within tags, bookmark titles, bookmark descriptions, and/or bookmark addresses.)
• 6pli.com generates these displays using one or more del.icio.us accounts.

There are other neat-o models, such as:

• Delicious Soup You can see the relative sizes of tags and their relationships, but you can’t actually see or use any of the bookmarks!
• Mind My Map It’s “neat”, but too neat and tidy – it doesn’t work intuitively, at all. I don’t think that kind of “mind map” should be called a mind map. It’s “tidy” but it’s not well-organized. No use of colour or size. There are no connections between bookmarks and their tags. There is no way to re-organize the display to suit what you seek. (It’s not dynamic.)
• Personal Brain TheBrain.com’s Personal Brain can now be displayed (and interacted with) online. It is, to me, the most intuitive and engaging and useful interactive mind model – but I don’t think it has full functionality for tags, and even if there is a way to import bookmarks, I don’t think there is a way to synchronize bookmarks. When I last checked you had to pay $70 for it as a personal user, whereas the others are free.
