The chart below shows the results of a recent online survey from Forrester which states that only 16% of respondents trust corporate blogging information. Personal blogs are only slightly higher at 18% (do you believe me?) and newspapers remain quite reliable at 48%. However the clear winner at 77% is personal email from someone you know.
However, as expected, not everyone agrees with the results or what they seem to imply. Trust can still be earned, or lost, no matter who you are.
