Obsessed (or merely want to learn more about) Knife Maintenance and Sharpening? eGullet has a detailed guide to knife maintenance and sharpening
Website and Blogs are adequate if you need information but sometimes you have a unique question that is best answered by another enthusiast. There are a wide variety of forums on the Internet where people will help you answer your specific questions.
An Internet forum, or message board, is an online discussion site. It originated as the modern equivalent of a traditional bulletin board, and a technological evolution of the dialup bulletin board system. A great deal of my initial knowledge of computer systems came from dial up BBS’es–to this day I remember the phone number of long-gone BBS’.
Now before you go off and start posting in a forum, you need to learn a bit about forum etiquette. My first bit of advice–read a few of the existing forum posts. Reading forum posts will give you an idea of the style of that particular forum (is it closer to a neighborhood club or more like a university classroom). Pamela Stevens has a good list of 25 Forum Posting Etiquette Tips that are worth reading.
Photo Freeware (http://www.photo-freeware.net/) has put together a great collection of free photo software. Need a tool to resize your photos, it’s there…a tool to do panoramas…you can find it. Well worth a look around.
A lot of my friends buy cameras based on the number of megapixels and then expect higher quality images. Image sensor size (actually sensor density) has a much higher correlation with image quality than the number of megapixels. Larger sensors typically capture images with less noise and greater dynamic range than smaller sensors. Wikipedia has a great graphic that illustrates the size of sensor found in most common cameras (click for original graphic size). Sites like dpreview.com offer statistics on image density. Consider sensor density when buying your next camera.
