I’ve recently started using my account at Flickr a lot lately and am really getting interested in all the tagging options that you can use. For those who aren’t aware of what “tags” mean in a technological sense, it’s basically a collaborative way for people to organize a lot of different content between users of particular websites.
So I upload a picture to Flickr and assign a bunch of tags (keywords that describe it), such as geology. For example, my picture of geology tools has various tags that I associated with it: geology, notes, rock hammer, rocks, and field notes. Now if someone searches any of these tags, this picture will be shown along with any other pictures with the same tag.
It allows you to easily find unique pictures of a similar subject. Here is a list of interesting geology pictures found on Flickr (though note it is mostly pictures of geologic structures and formations).
Other websites allow you to search by people’s tags as well: del.icio.us geology bookmarks, geology videos on youtube.com, and geology blogs on technorati.com.
