Same problem here with Chrome 15.0.874.83 beta & Ubuntu 11.04. With Opera 11.51, it just shows the Markdown source. With Konqueror 4.6.5 it opens the file in gedit. I suppose these are all different symptoms of the same issue which is that the drop event doesn't get handled as expected.
It works great with Firefox. Very interesting tool!
