Twitter has been a revelation for Kate Nelson, helping to control her inbox while she works on her beloved Mac. Other top sites help her to practise what she preaches on sustainability at home and in the office

Favourite website?

I am hooked on etsy.com, which sells handmade items from around the world. It links me into UK-based designers and artists. As someone who works in responsible procurement, I love buying one-off items.

Favourite gadget?

I became a Mac user last year 鈥 it was love at first drag and drop.

Most useful website for work?

The best way to get the latest information is to stop subscribing to email newsletters and follow your favourites on Twitter. It keeps your inbox clear and you can choose what to follow up on.

Last track you downloaded?

I am all about spotify.com, where you can listen to most albums free (legally), but the last download was Useful Chamber by Dirty Projectors.

Subject of the last email you received?

Skittles! We are building an intranet for our sustainable design lab. We have been inspired by Skittles.com. It plugs into Twitter, Flickr and YouTube to generate content, so it is by the people for the people.

Walkit.com helps me avoid spending time cooped up in taxis or on the Tube

Kate Nelson

Social networking or face-to face?

Hard to say. I am a fair-weather friend of Facebook but can see its potential. At this stage I prefer a conversation over a pint of ale.

Favourite blogger?

My friend Charlotte, who is on a cookery bootcamp in Ireland (http://chopchop-charlotte. blogspot.com). She works for Sustain and has helped me be a more ethical eater.

Best link you鈥檝e been sent?

Walkit.com 鈥 we are based in London鈥檚 Victoria and it helps me to walk to all my meetings instead of being cooped up in taxis and the Tube.

What was the last thing you bought online?

A fruit and veg box from Abel and Cole.

Funniest piece of spam?

Spammers have become so lazy, I haven鈥檛 had a good piece in ages. But I did hear a funny story about a big tunnelling project and a filter that deleted emails which included the word 鈥渟haft鈥.
