When I went to uni, more years ago than I care to remember, I would return home from time to time at the weekend, and go out with the lads on a Saturday night. As it was a rural area, we'd drive to the nearest big town, visit a pub and then go on clubbing.
We'd usually visit the same pub, but every few months the pub we went to would change.
Why?
We didn't go to the pub with the best beer, the best music, the best seats. No, we just went to the "place where everyone else went". From time to time, everyone in town would get bored with one place and move on somewhere else which then became the new "place where everyone went". That made it (for us, at that time) the place with the best atmosphere.
What Dice needs to realise is that all that Slashdot is is one of the "places where everyone goes" for computer / techie discussion (OK, so it's not the only one, but you get my drift). This site has no value, other than being the "place where everyone goes".
It won't be at all difficult for someone to set up Dashslot, or Slushdirt or whatever, with the same formula as traditional Slashdot, and once word gets around that new site will be the "place where everyone goes" instead of here. Slashdot will become the new Kuro5hin, a steep and tragic decline from former glories.
And that new site might even have decent editing and Unicode support.
