Photo sharing

Most of you will have heard of flickr or other sites like picasa where you can share your images. Though these sites are not a portfolio, they still represent your work, so while you share more images on them than you would on your own web page you still need to consider the content. All images should be in focus, sharp, exposed properly and displayed correctly.
I have over 4,000 images on flickr with over 150,000 views, my hard drives have over 20,000 images on them and god alone knows how many that has been lost/deleted over the years. Thats a ratio of 1 of every 5 keepers that are good enough to share.
