As you can see there is no more 1 word top level domain (tld) available for register (or only few word domains left; read as dropped) and today i just manage to get the dropped domains information and here is the list.

exclamations.org
frisking.info
generalize.us
glided.info
insular.org
perhaps.biz
redeems.org
reformats.info
unfold.org
unshaken.org

Maybe you gonna think that these domains are worthless but for a domainer out there, they think differently for purpose of future investment. Well, i will list more dropped and worthy domain in the future.
