Here's an idea...
... now someone go and implement it.
Brindy has started 'twittering' to his lj recently which mean that anything he posts on twitter is collated and posted as a blog entry at the end of the day. Now this is a great idea if you use twitter but I don't, nor would I have any plans to.
Instead I want a similar thing that would work with my pedometer. It's a bit 'Bridget Jones' but I like the idea that I could just wear my pedometer and it would send my daily total to my PC or to a piece of software that would write to my blog. If it's happening already then I want to know about it, otherwise feel free to take my idea and implement it. Just remember to send me a free one - for testing obviously.
