My initial experience with Twitter echos this statistic. I tried out the service and quickly grew frustrated and gave up on my account. However I rediscovered Twitter about four months later.
The difference between my first and second attempt was that when I returned I only shared “purpose-filled tweets.”
Like my mother would say “if you don’t have anything [nice] to say then don’t say anything at all.” I think this also applies to Twitter. It is a good idea to know how you will use the service before you sign up. For the person on the street, Micro-blogging can quickly become much like shouting into hurricane-force winds, an exercise in futility. If you have purpose behind each and every post it can actually add value to your personal and/or professional networks.
