Indeed, many different flavors and options! We started a spreadsheet to compare features of several different platforms which are related to Metamaps in terms of basic functionality and use cases:

I will harvest from this thread here into a thread on transformap discourse so that we can track further additions - it is an interesting area of development these days, bridging communities of practice into the semantic web :)

Ben, Michael, Silke:

I also joined metamaps and it has some really nice features regarding the way you can include and exploit external links.

I recently started a conceptual mapping sprint in Vienna, but we postponed it after one day because we are still looking for the best way to integrate the features of dynamic mindmapper, database with tag & key fields and html links to wikis

I would really appreciate if we could have a good comparison between conceptual mapping tools in this respect.

I noted some links here: http://www.dorfwiki.org/wiki.cgi?Mapping (sorry, in German) but its only scratching on the surface.
Nevertheless I was totally surprised by the plethora of collective conceptual mapping efforts available!
