It’s near impossible to find someone who doesn’t use a Google service, whether it be Gmail, their search engine, Google Reader or whatever else. The problem with using all of these services is that all tranmissions, minus the login process, are unencrypted and ready to be viewed by prying eyes. In a home situation this doesn’t matter too much unless you have a rebel family member, but in a workplace, -anyone- could easily be running a program like tcpdump to view your e-mails and the like. Daniel Miessler has a good idea for those looking to secure themselves… simply change the http:// to https:// to engage a secure connection.
The more we depend on Google (or any other monolithic service) the more we need to safeguard the information they have of ours. One way we can help is by demanding (via secure bookmarks) that they send our mail, news feeds, calendars, and other information over a secure connection.
