Can anybody name a specific situation in which they've been inconvenienced by not allowing third-party cookies? I've always had them turned off, and I don't think I've ever not been able to do everything I've wanted to. I realize that this is a hassle for people like facebook/google, who want to be able to track us as we move from site-site, but I'm wondering how often it negatively impacts the individual user?
I don't think it's universal but I've been on sites where I've been forced to enable it to use their commenting platform (cant recall if disqus or intensedebate).
It's either no longer a problem or depends on a site's implementation though because I've used both platforms without 3rd party cookies recently.
I think that might happen if you try to log into StackOverflow with an StackExchange account. I swear I've seen the message Please turn on 3rd party cookies somewhere on that page... It's a very simple thing, but I really can't try it now! I'd be grateful if you could test it.
