Rather than suggesting that people delete their cookies, you could suggest checking the article in private browsing mode (or whatever their browser of choice calls the feature).
I can't believe this bug still exists after two years.
Maybe it's not a bug then.
No it's the usenet remnants, not google+. But yeah, google made usenet worse too.
You have to login? It doesn't do that for me, and I'm not logged into any Google products...
Same here.
Google has invented a new login state between "logged in" and "not logged in" called "not logged in enough". It's kind of like being logged in, except nothing works and you get asked to login again. Also, you can't logout.
You can log out. You click "log out and log in as a different user", and then bail out. Then you can use Google's public-content products.
When it happened to me, no, I couldn't. I click logout, then the browser redirects, and hey look, I'm still logged in. Kinda.
Delete your cookie or sign out. It's just a Google Groups thing for you to refresh your session and I dunno, parallel login or something (they may never have completed the dejanews cutover). Unknown users don't get a login prompt.
