I'm considering a swap from Movable Type to WP, and finding the WP post-id numbering system confusing as my WP install is assigning them in a manner other than I'd expect.
As the default 'hello' post is, as expected, numbered 1, and the default 'about' page 2, I'd expected new posts to be sequential incrementing as 3, 4, 5, 6 etc.
But the assigned numbering is 4, 6, 8, 10... It's this I find odd.
Is this normal, and if not, id there a way to have sequential IDs assigned to posts?
