Someone wrote to me recently, asking for my opinion of two other business professionals. Because I am in a professional group with them, she knew I could vouch for them.
The reason she wasn't sure whether they were reliable, successful people is that their websites were woefully out of date. One hadn't posted on her blog for four months. Another listed "upcoming classes" that had happened in March and April.
Whatever positive things I could say about them were diminished by what their websites communicated.
What do out-of-date websites say to you?
