Flickr is my photo site of choice right now. Ideally I would like to generate similar features using Gallery (which I have hosted on my site too) but I don't yet have the time to sort all that out. So, right now, Flickr will do me very well. I am pleased to learn in their recent blog post that they are Canadian (I have such a soft spot for Canada) and - what's more - they are based in Vancouver which is where we're planning out holiday next year. You weren't really interested in that were you?
