WSJdpatton writes "Marriage often requires coping with the loss of some individuality, whether it's adopting a spouse's last name or setting up a joint bank account. Now, some couples say it can be equally tricky to navigate intimacy in the digital sides of their lives. They are running into thorny questions regarding how much to share and how much to keep separate in areas ranging from email addresses to online calendars. For some young newlyweds, this means a debate over whether to combine their blogs. Longtime spouses, meanwhile, say perennial arguments about who has more closet space are now joined by bickering over which TV shows get deleted to make room on the TiVo."
