There's a difference between a bug and being tied to a platform for one application. To be fair, you can always switch to another OS (or even another distro) and use chromium.
While I largely agree (and have found that G+ actually is pretty usable under FF16), the point I was highlighting is that Google are (for somewhat understandable reasons) pushing very hard at the concept of what a Web browser is, and what it's used for (they really, really want it to be an app platform, not just a media presentation tool), to the extent that their site degrades significantly under other browsers. Which creates a pain point when Google's own browser fails to function under my preferred OS.
And I don't really see scrapping that OS just to use a single website. There are other alternatives (VMs, etc.), but they're not particularly attractive either.
The IOS6 specificity of The Magazine really is pretty brain-damaged though.

Edit: clarifying, G+ tends to strongly favor chromium, and the latter's broken as of my most recent update.
But, yeah.
