No idea, perhaps they're just too busy, or maybe they have too many people trying to get their reviews listed, i don't know.
But why do you want to get yours listed on DW? You have only 2 reviews. Be patient, let it be at least 20, get visible via google, people will come and if your articles will be any good, they will come again and then you won't need DW. ( And then they will get you listed
But please, don't ever use liveCD for review, anyone does that and noone
really cares about such 'reviews'. Make a partition and install on iron. Better yet, try to actually use it. For example, openSUSE 12.3 would be about 4-5/10 from me and just because it's really nice, fast and polished. But it has this fun bug which causes memory leak in X while copying large (100GB) amount of data, eventually crashing X. This is severe structural damage in my dictionary and reason to instantly dump the distro. Point is, you won't notice this in Virtualbox, you have to use it.
