Back in March, we asked you to send us your best idea for a gadget, app, service or some other slice of tech genius for the chance to win a week's worth of mentoring by Google's experts in our Stuff Launchpad competition.
Hundreds of you submitted ideas that were everything from completely brilliant to completely insane (many thanks to the guy with the electronic spoon, you nearly made it), and after hours of deliberation we picked six favourites to pitch their ideas to our judges - Russell Hall, co-founder of taxi app Hailo, Oleg Fomenko, co-founder of Bloom.fm, Niko Schröer, Google Office Hours mentor and Simon Osborne-Walker, editor of Stuff magazine - at Campus London.
Here's our third finalist, Gillian Edwards, with an idea for a social network for the elderly. The loneliness and isolation faced by many elderly people is one of the biggest but least visible social problems we face today, and while technology has enormous power to help, it tends to be aimed at the young. That's why Gillian recommends keeping it simple, and enlisting some young 'uns to help out.
