It took me a while to figure it out at first, but now I'm addicted to Flickr. Photo sharing - what a concept! It's like candy for the eyes. It's like ebay without all the pesky bidding. Pictures are posted on Flickr merely to be appreciated. People are sharing their perspectives and in turn, others post comments on how the image moved them - "This reminds me of. . ." , or how they relate to it - "I have that same mug!", or how they simply appreciate it - "Great job!" I've found it to be a very positive community and a nice place to visit when I just want to look at pretty things.
Like Pyrex, Vintage Fisher-Price Toys, Thrift store finds, handmade handbags, plush creatures, art studios, craft shows, the corners of people's homes, babies, gardens, etc. etc.
If you look at all the groups a person has joined you can get a good sense of what they appreciate. What are you into?
Bugs? Boogers? Hot air balloons? Bubble gum?
Whatever it is, I bet there's a Flickr group for it. If not, then start your own! Someone out there will want to see your pictures.
