This has been mentioned before: my wife and I do a photo a day as part of 365 Project. We use it as a kind of visual diary.
Don't confuse this with Office 365, which is Microsoft's way of ripping you off with its subscription service. Open Office does as good a job in my view for free.
Back to 365project. This is free, but you can pay $19.99 a year to make it private and have additional benefits. Some people use it as a platform for very "arty" photos. Many, like us, post very average photos of our very average lives. It is great fun. You don't need a flashy camera. I got most views with a photo taken with a cheap device with low resolution.
