While Opera users sometimes find sites that discriminates them due to bad browser sniffers, the music site eMusic seems to make its own twist on the situation: According to this article on about.com, eMusic presents different offers depending on which browser you use, and which OS. Opera users get the best offer, and Firefox users the least.
How long will this situation last, now that it’s brought forward in the news? No idea. Maybe I should go and have a look? With Opera, of course.
Hmmm – just had a look. I didn’t get such a good offer as the article writes about, so it may be changed already – but I haven’t tested with other browsers.
UPDATE: It seems to be completely random after all, not dependent on which browser you have. I just saw the same thing mentioned on Opera Watch, and the comments there show very different results.
