Yes, I do check for collisions because I was also curious.

I'm not using an autoincrementing primary key because an autoincrementing primary key depends on the state of the table within a given database. My data sits in Google App Engine for production and sits in a postgresql database as the primary source for when I need to curate it. (Processing directly on G.A.E. costs more than transferring the difference periodically.)

    Could you describe how please?

    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.
