by @edent | # #
A goldfish, with a shark find stuck to its back.

In How to Make the World Add Up, Tim Harford draws on his experience as both an economist and presenter of the BBC’s radio show ‘More or Less’ to take us deep into the world of disinformation and obfuscation, bad research and misplaced motivation to find those priceless jewels of data and analysis that make…

First they ignore you, then they laugh at you, then they fight you, then you lose

I've just read an interesting article by M.G. Siegler entitled - "What you’re working on sucks, just give up now, they said." It can be summed up thus: Commentators said our startup wouldn't work. Our startup did, in fact, suceed. ∴ All commentators are wrong about whether startups will work. This exhibits one of my…

Sex Ratios in Delhi

There are no words to adequately describe the horrific rape and murder of Jyoti Singh Pandey. I remember, several years ago reading a short piece of speculative fiction which postulated that China would go to war over access to women. Generations of female infanticide would leave the country with a severe gender imbalance. Hoards of…

Wandering around the steets of London, I came across this excellent initiative from Camden Council on how to use QR codes on street furniture. If you see that a light - or anything else - is damaged, you can scan the QR code and report the issue. There's even a phone number and vanilla URL…

The Perils of URL Shortners

I'm not a big fan of URL shortners - bit.ly, t.co, goo.gl, ow.ly, etc - I understand the need for them, but they seem to offer a fairly poor service in terms of privacy and usefulness. Take this recent example from Vodafone. Aside from the obvious downsides (user doesn't know where the link will take…

No, I'm not talking about Masabi's innovative technology, but of this rather odd bit of advertising found on the back of a train ticket. There's no specific call to action - but there's not much space to play with. Let's give it a scan... *sigh* A non-mobile site. With an Adobe Flash plugin in the…

TfL QR Followup - 5,000 scans per month!

by @edent | # # # # # | 6 comments | Read ~476 times.

At the start of 2012, I revealed how many scans TfL's QR campaign was getting. A lot of comments on Twitter & Google+ dismissed these results as a success. A typical response was: 70 scans a day? In a city of millions? Rubbish! This fails to address something that advertisers are conspicuously loathe to reveal…
