TXKimmers perfectly sums it up:
And I have discovered why Flickr is so ideally suited to me--for an intellectual magpie like me, it's a huge pile of shiny tinsel. One thing I have learned about myself in 40 years is that I like to know a little bit about a lot of subjects. Mastery of anything is anathema to me. And Flickr is a magpie's delight, stimulating in so many ways, but forever dishing up new and shinier distractions.Exactly.
