People often ask me what is the use of Twitter. I give them my answer but I usually find it is best to give them examples of how it has helped me or other people I know.

Here is another one. Paul Gillin is a US based author. I loved his first book 'The New Influencers' so much I interviewed him for a podcast. I highly recommend his book so when he posted via Twitter and his blog that he was sending drafts of his next book out to 250 people lucky I tried to request a copy. Sadly, due to cost he is only posting them out to US based people.

This is what he just posted on Twitter...

Power of Twitter: Free book offer (http://tinyurl.com/5cos49) gets 7X signups in 30 mins on Twitter as in 24 hours on three blogs.

So now I can add 'sales promotion tool' with an example to my list. 

Next time I speak to Paul I must as him how many people follow him on Twitter versus read his blogs. I bet you that his Twitter followers are lower which makes the above comments from Paul even more interesting for marketing people who need to get news out fast and wide.
