Post History

When we set up this site we imported from SE as of the December data dump (the latest we had at the time).  We didn't have a way to get the delta; the import code didn't use the API.

We now have better data-import tools, and there's been a new data dump.  We can, therefore, import stuff that was posted on SE between December and now -- through sometime in March via the data dump, and through the API for the rest.  We can also now specify what we want via a SQL query, so we can make import decisions based on tags, question status, votes, whether the question has answers, and more.

This is for new *posts*; we can't integrate *edits*.

I think it's worth pulling in more posts, as some of our users here were still active there during this period of time.  I also think it's worth being a little more picky than we were on the initial data load.  I'm thinking about excluding anything that's downvoted on SE, and any question that's closed.  Is that a good approach?  If not, what should we do instead?
