In addition to my other jobs/interests, I also run a blog dedicated to atopic conditions, like allergies, eczema and asthma. There are a lot of blogs about allergies, but not a lot about all three. The same goes for sites about restaurants and reviews. Lots of sites, but not a great deal for those with allergies - until AllergyTrails. Since I love eating out, I contribute as much as possible to what I hope will become a permanent resource for those with food allergies - worldwide.

For the sheer scale of the project alone, it's definitely worth checking out. And, if you have allergies, or know someone with allergies, please consider contributing. You're actually making someone's life better in an appreciable way.
