Hong Kong-based man is TripAdvisor's top reviewer with 3,200 posts

For travellers around the world, its more than 200 million reviews and holiday tips are invaluable in deciding where to stay, eat and visit. But as TripAdvisor celebrates its 15th anniversary, the website has revealed its most helpful user of all - Hong Kong-based American Brad Reynolds.

Reynolds, 37, director of a learning centre in Fo Tan, has written 3,200 reviews, making him the website's most prolific reviewer. He has given his take on hotels, restaurants, shops and tourist attractions in more than 30 countries.

He joined in 2009, but it was only during a trip to St Petersburg the following year that he decided to start posting reviews.

"We received so many good tips that we thought maybe we should start contributing, too" Reynolds said.

Critiquing holiday destinations as well as places in Hong Kong was now a part of his normal routine, he said. "It's an enjoyable hobby."

The couple go on about four big trips a year, each lasting a week or two, with shorter breaks throughout the year.
