A few years ago I started writing reviews of books at Amazon.co.uk. On 21st July 2001 I wrote a review of The Life of Mahatma Gandhi by Louis Fischer, and Hell's Angel: The Life and Times of Sonny Barger and the Hell's Angels Motorcycle Club by Sonny Barger.
As of today - I have written 46 reviews of books, music, gadgets, and movies. I am currently ranked as a Top 500 Reviewer - my position as I write is #364. I have 496 "Helpful votes" from other reviewers, it is nice to know that others found my reviews helpful.
Writing reviews is one of the great features of Web 2.0. You can not only let others know what you think of products, but also I often read reviews before I consider purchasing something written by someone who has already bought the product. Amazon also use this information to help make recommendations to me for future purchases.
Most of my reviews are positive, though I point out rubbish when I see it. To read my reviews, click here.
