The once-trendy social network site has been shedding unique visitors at a rate of around five million a month, according to Compete.com, a web analytics firm.
It's a grim warning to anyone hoping a free website can survive from community participation alone, and should give pause to all internet media owners, from individual bloggers to Ted Turner.
Free Exchange suggests the collapse in users amounts to a near-irreversible freefall - once your friends stop being on MySpace, you stop going there. And so do your friends.
Web 2.0 growth spurts point to two things: the fragility of social networking sites and the resilience of clunkier competitors. Twitter or Facebook may well suffer the same lingering demise against nimbler rivals. But look at other service websites - for some variety, let's pick email, torrent sites, and news - and you'll find a great deal of brand strength that, whether profit-generating or not, trumps Web 2.0 upstarts every time.
Email eludes MySpace's problem, because even if you're still using your rickety old AOL email you picked up before the dotcom boom, you can still communicate with anyone else who has an email address. With most Web 2.0, this isn't the case - you're limited to other users.
Torrent sites - i.e. sites used by pirates to find illegal software and music - have an inbuilt bias towards community participation - they need users to locate and vet pirate downloads found elsewhere online, but a community alone doesn't build a torrent site. The key factor for the consumer is links to other torrents. Two Somalians in a raft could do that.
News also avoids the problems of Web 2.0 because it has been so stubborn in face of the communitarian spirit of the blogosphere. Removing the comments section wouldn't affect unique users. Newspapers can lose community engagement, and people will still keep coming back, albeit in increasingly dwindling numbers.
But comments affect time spent on a website, and that's important. The biggest money spinners for newspapers have been broadcasts of events in the real world lasting more than an hour, like Barack Obama's inauguration, and football games. The recent England-Ukraine game pulled in half a million viewers, each paying a fiver, but the amount of time a user spends parked at the same web site makes it a gold mine for advertisers.
But wait! Football games share a quality with MySpace and other Web 2.0 programs - they're miles better when you're with your mates. News media knows this - CNN has already been providing streams of Facebook comments alongside live events, which have proved remarkably popular.
Could news websites provide a portal for people with related interests to view events and form networks? Media companies seem to think so.
But the death of MySpace will haunt all such efforts as a warning of how quickly community-based websites can be abandoned by users, and will give pause to any CEO hoping to drive company revenues with Web 2.0 tools. Of course, any penniless blogger could have told you that.
