You blacklist a site based on that it doesn't work on a web browser that isn't even on the list of the 10 most used browsers? (src - http://www.w3counter.com/globalstats.php)
Why not? The web browser in question is basically just FF10 with a more OS X friendly UI stapled onto it. The site owner shouldn't have to do anything special to get it working in Camino, just don't make it the most over-the-top and animation-heavy blog you can.
Google chose to ignore that, and they're rightfully catching flak for it. This isn't some fancy homepage, it's an informational blog. Text on a white background is the reason 100% of visitors visit. Hamming it up at the expense of non-mainstream browser users is pointless.
