It's not the cheeriest subject to contemplate, but when you die there'll be bits of your life splattered all over the web and out of your control. Life Insurance Finder has a handy roundup of the "death policies" that apply to popular services such as Facebook, Twitter and YouTube, as well as a discussion of your options.
What happens after you die differs from site to site, and some sites make it more difficult than others. Most sites will shut down an account if supplied with a death certificate, but that might not always be the best solution: Flickr photo albums, for instance, have value even after you've passed on. Ultimately you'll still need to plan for dealing with this situation and work out who you're willing to share passwords with, but knowing the options can help. Hit the link for the full post.
