I happened upon the Digital Photography School web site the other day and found it to be a great resource. Regardless if you use a point and shoot camera or a DSLR the tips, forums, and Flickr group are great places to find answers to any questions you might have. The current posting is titled 16 Digital Photography Tips for Christmas.
Two other resources I have found recently are DPReview and FredMiranda.com. DPReview is is one of the primary sources on the web for extensive reviews of all digital cameras ranging from point and shoot to high end DSLRs. They also have great forums with info. on cameras, lenses and almost any other accessories for digital photography. FredMiranda.com is a site that collects reviews on digital photography hardware from a vast number of members, many of whom are ether professional photographers or long time amateurs.
