I've updated the profile links to show several new services I've joined recently, including identi.ca and Goodreads. For those of you unfamiliar with Goodreads, it's basically a social network that allows you to record what you're reading and post reviews of books you've read.
I myself have just finished Charles Stross's excellent new novel Saturn's Children and have posted a review there (although I can't find the cover for the UK version). I really love this book, and highly recommend it to anyone with a liking for SF of any kind. For more details, please see my review.
I'm now reading Stephen Baxter's Flood, about a future where sea levels begin to rise, and don't stop. Ever. Once I've finished it (which probably won't be long as I don't have Internet acces at my house in Norwich so I have little to do, and it's so far been a very enjoyable book), I'll do another review. In the meantime, why not check Goodreads out? It's a great service.
