NYT Book Review
Useful ? - I don't know, probably not for me - too much information overload; too much stuff to weed through for what I might be interested in. Good for both work and leisure, but I don't choose to have the time either at work or at home to spend on-line. At work I'm too busy, and at home I would rather read, garden, cook, craft, socialize with family and friends.... I don't have enough time in the day to do all of that, and I don't watch any tv (don't even have one!), or read magazines or newspapers.
