I helped writing the Alexa skill for The Guardian [0], and I really didn't think highly of it, nor I thought I'd ever use it myself: the voice recognition is still poor, and it's difficul to understand what you can/cannot do with it. All in all, a big meh.
Then one day someone forwarded to our team this email, and it really touched my heart.
I am quadriplegic and the Amazon Echo has transformed my life. I haven't been able to open a newspaper for 10 years, but now I can! [...] Please pass this email on to all of those concerned at the Guardian... They need-to-know the difference that they have made".
