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.

The one in Wikipedia is very general...http://en.wikipedia.org/wiki/List_of_concept-_and_mind-mapping_software

shareable has a nice review: http://mashable.com/2013/09/25/mind-mapping-tools/

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!
