Ive been using Lynda courses for a long time (since ~2003) to get a head start on new technical topics like Microsoft and Cisco products. Back then I bought courses on an individual basis, which proved to be a bit expensive for dabbling and only added value if the topics of interest were very well defined.
Recently my library became a subscriber to Lynda.com which resulted in access to Lyndas complete catalog of products - since then, Ive spent a lot of time discovering new topics. Love the service and the products.
