One of the absolute core tenets of Slashdot has always been that they don't delete things (unless someone sues them for a billion dollars, and even then, only once). It's important to be able to prove it if it happens.
Indeed, which is why talk of post deletions is so important to verify. Has it really become that kind of site? Just another barely concealed attempt to exploit an actual community into providing advertising impressions?
Deleting posts would be the death knell for me. The way we use the site is important, but the ethos of it is moreso. A Slashdot that arbitrarily deletes things it deems unwanted isn't one I'd like to contribute to.
I'm sure we'll find out, one way of another.
