Interesting. Removing the ?share=1 has no effect if you've already visited the site, but opening the plain URI in another browser blurs the answer as usual. It must use cookies.
In other news is anyone else still put off by the site even when it isn't all blurred? Its kinda weird I still get a gut rench feeling looking at their logo. They got a ways to go I guess.
More seriously, thanks, sometimes they are useful and the share hack will come in handy.
I definitely dislike the blurred answers scheme. I think I even had Quora blocked from my searches when that was possible (without a plugin). Sometimes, though, they look like the only hit likely to provide useful info to a question I'm really interested in at the moment, so I eventually gave in and just removed the friction of reading the site by installing/making plugins for it.
