I have no reason to assume he was actually looking at it, but McGehee would have been the first person to be able to see this little callout over in the sidebar last night:
And actually, that’s 50,000 just since September 2006, after the first Movable Type database was closed down and all the posts converted to static pages. (The second one was successfully imported into WordPress two years later.) So this figure includes the last two years of MT and all the years of WP; there are about five years of comments — 17,000 or so — which are not included in this count.
Before you ask: of those fifty thousand, about 9200 were written by me. And I have no idea if this little gadget, not formally a widget, is capable of six digits. Maybe we’ll know in ten years.
