Forums
A really great way of learning photography techniques and meet other photography enthusiasts is partisipating on the photography forums of the web. It's also an easy way to get other peoples comments on your work, and to comment on others. Remember; be nice and polite, and you will get planty of help and feedback. I have learned so much from the good people of these forums, and particularly those at the dpreview Olympus Talk Forum. You guys are the best!
Here are a few of the forums I visit.
