anything rails based app like pligg or digg out there ?

I am wanting to do something like digg but internally at our company
and am looking for a rails based starting point. There is something
out there called pligg which seems pretty good, but it is PHP based and
I expect to be making quite a few changes/additions, so would really
prefer a project based on rails !

- hope to hear from you

i guess you want the voting algorithm and how items are sorted?

More looking for a whole site, pretty much like pligg
(http://www.pligg.com). Kindof like a typo type thing, but instead of
for blogging, for a digg like site.
