I bet Sunken Civ has a few Google automatic search terms set up on things like archealogical, fossil, "clovis point" etc.
The automated searches that I have set up for work certainly turn up some odd publications. Then when I forward the story to someone they think I am so informed to be reading so many different news sites.
Maybe I need to figure out how this PC thingy works.
My semi-automated search engine is FR.
