(As always you should take some of the information in those Wikipedia articles with ... a grain of salt!)
I should issue a caveat from the start: I'm not a formally trained linguist as such, and certainly not with respect to the Chibchan or any other native American languages. On the other hand, I do have a kind of ... general background in Indo-European languages and linguistics thanks to a bachelor's degree in Folklore & Mythology (Medieval Scandianavian) and a doctorate in Anglo-Saxon, Norse, and Celtic studies, so the problems and issues of research in (what a Colombian anthropology professor marvellously described to me as) chibchología are not wholly alien to me. In any case, the field is so poorly known (though there are a few very great experts scattered around the planet here and there) that I can hardly make things worse with my musings.
Perhaps, in time, a wider electronic academic forum for chibchology might come into being. Until then ... this will be a start!
P.S. - I spotted the phrase "Se habla chibcha" on the tablecloth at the Bogotá restaurant/nightclub Gaira owned by Colombian folk-pop star Carlos Vives and ... well, I want the T-shirt! :) Good place, by the way, with tasty food and awesome live music!
