Digg is still alive. Myspace is still alive. These big brands don't literally die often; someone will want to try and play around with it.

Twitter is technically stable in terms of servers. They did a good job doubling up by 1) minimizing the load needed by making users sign in to see more than a literal permalink (you can't even see comments anymore) while 2) being a bait to get more new accounts to report on engagement. Not that that matters now since Twitter is no longer publicly traded.
It's the everything else around it that caused it to plummet.
