Fab, which now has up to 9 million users, is introducing Holiday Shops to help users find gifts for the holidays. The Holiday Shops are organized into 12 categories covering gifts for best friends, parents, design or pet lovers, him or her, or gifts for specific amounts. These shops were introduced last year but were limited to two categories. The Holiday Shops will be available in the top left corner of the website, another change in Fab.com’s redesign. Fab started 2012 with 1.5 million members, raised $105 million in July and is moving four products per minute. (GigaOM)
