First, use tags well. This is the newest style of organizing things for the hierarchically-challenged. Actually, computing has become so much less organized since DOS days when each and every subdirectory was loving created with the command 'md' and one moved around by 'cd\'ing all over the place. On flickr you won't be worrying about making folders as new photos will just appear in your stream. After you have more than a half dozen, it could be hard to find what you want. Therefore, plan and use your tags well. For example, from the 50 plus photos on the site today, you can view new westminster, burrowing owl, or 1970. It will even keep track of all the tags you've used.Second, get all your digital-imaging friends involved in Flickr right away. This is because you will have instant access to their uploads whenever you sign on. Right on the first page you'll see photos from your contacts. You might want to allay any fears of those who think privacy is important. They can specify photo as visible to only those deemed as family or friends. Personally, some people go a little overboard about privacy, but then I'm a blogger who just loves to have people stop by and gawk.
Next, an absolutely amazing ability of Flickr is the use of groups. Each of one's individual photos may be offered as visible to a group. That means you search the thousands of topics started by others and contribute matching photos to them. For example, I shared many photos in an official Beautiful BC pool. Do you have a really off-beat topic? You can create your own group and hope others will stop and participate.
Lastly, there's more to each photo page than originally meets the eye. Explore the lower, right-hand side of the screen. For some photos that haven't been edited you may even see the option for more properties. You might even learn some information of which the photographer wasn't aware!
