- I find writing reviews relatively easy. Always have. Right back to those halycon days scraping the bottom of the free CD pile for the student newspaper.
- Reviews sharpen opinions - it's a way of working out how I think or feel about something. Or how I feel about something now, in the case of some very early posts about fantasy novels I used to treasure by Donaldson, Eddings and May.
- Communicating my enthusiasms to others. I accept that I'm not anyone's primary source of information on, say, Iron Man 3, but the best recommendations come from friends, right? And I just might be someone's first encounter with Ulver or Spider Robinson, or provoke an equally enthusiastic response.
- Making a broader point - sometimes a review spills over its boundaries and allows me to board a wider train of thought, like the wierd as an antidote to post-Tolkien cliche in fantasy, or the rugged modernism of metal music.
Edited to add: I read a lot more than I actually review, so I've just signed up to Good Reads to share my reviews there, rate books I read but don't review, and see if I can pick up some more recommendations for my fairly eclectic tastes.
