When you have a Flickr account, it acts as kind of a "photo blog". You life, captured in photos. You can join groups and have others comment on your photos and find people who love the same stuff as you do. For example, I like to take photos of my food. And of my tea. And of my coffee. And of weird things. I found out that lots of other people do too!
There is just something mesmerizing about photos. Capturing the exact moment of an emotion...pure bliss.
And yes, I do have real friends and a life outside my computer.
