Of course they were intrigued and wanted to know every last detail.
It took me around, a hour to explain the basics to them over a skype call, at the end they were all confused and had no idea what I had just told them, one even said "That is no possible", what is not possible, I asked.
He said a online currency, I laughed and ended the skype call, lol.
Anyway, the point is bitcoin is in need to be simplified and I THINK a lot of people agree on the subject, the whole mining bit is confusing even for veterans of bitcoin.
I've explained Bitcoins to 2 university undergrads yesterday and it took them quite some time to get it. I don't think the mining aspect is all that important but it's the implication of Bitcoins that is hard to get right away... It can take some time for it all to click in.
Of course, there are people who just don't care or want to understand anything outside of their comfort-zone. Bitcoin is funny like that, it's a great barometer of one's aptitude to adapting and accepting new concepts... some people just aren't capable of generating self-interest even when the result would obviously be rewarding to them.
