Can I buy this in the UK? I clicked on the AppStore link on your web site which took me to a general iTunes splash page.

No, sorry, we aren't selling this internationally right now, because the Topo maps only cover the US and Canada. We will be releasing an international version, as well as two other apps that will be available near you soon: Gaia Maps and Gaia Places.

Maps and Places are cheaper and are standalone features from Gaia GPS.

IMO, entrepreneurialism is an inate human trait. However, this doesn't mean it's expressed in everyone you meet, day-in-day-out. It clealy isn't. It's possible technology is simply an accidental expression of this trait. Which is interesting yet terrifying if true.

I'm not sure what's ambiguous. Certainly I'm generalizing ("anyone") from an anecdote; I'm not trying to make a rock-solid historical claim.

I think most of her factory work was making shells. She was born in 1921; this would presumably been in 1943-45 or so.

What I meant say was it isn't clear to me if she was a worker or ran the factory.

Oh! Just a worker.

If you want to read something interesting regarding sponsored subversion, I recommend 'Legacy of Ashes' by Tim Weiner. Fantastic hacks and incredible, yet true and widely uncredited events in US and world history executed by the OSS and CIA.

I don't think we're using Twitterifics logo, but I'll check as that wouldn't be right. Thanks for mentioning that.

Looking at the exception log, this appears to have happened was when you tried to vote without providing an email address? I can't reproduce the error but will investigate further.

Good point. The business model for this site is to help small businesses survey their customers and employees which needs to be the focus for promo material like tag lines, FAQ etc. The objective is to grow a paying user base who survey people with little insentive to spoof their responses (like voting multiple times), which negates some criticism like 'why would anyone provide an email for a frivolous poll'.

I generally agree with you, however, from memory, I recall pg saying that entering a crowded market isn't necessarily a move that should be avoided. I think there's plenty of opportunities to beat established web sites by providing better solutions.

I agree that email validation is flawed in terms of ensuring uniqueness, so this is something I may drop and insist users create an account. One thing I have considered in the mean time is allowing registered users to hide non-signed in participants.

That'd be better. Make the default action when voting "vote as anonymous, unless logged in", and upgrade that anonymous vote to a registered one if the user decides to register after voting.

Also, having an account is not ensuring uniqueness either.

Interestingly, one of the main criticisms I originally received was that you could vote without providing an email address!
