Why this list? If you search for "privacy" on Twitter, there are some experts, but also a lot of junk. So, we decided to compile a list of the most influential voices in the online privacy debate.
The list is based on Twitter data culled according to content, follower/following ratios, frequency of tweets, blog popularity, the opinions of other privacy experts and our own subjective judgment.
One note: There are influential voices who are not included because they don't have active Twitter accounts or they only tweet about privacy sparingly. Our goal with this is to provide the best possible stream of news and insight in the privacy debate. While no list will ever be 100 percent on-topic, this factor does eliminate some who tweet on a wider range of subjects.
Did we miss somebody? Let us know.
