Query: have we “officially” launched yet?

Um, so, I’m unclear as to whether or not the site has “officially” launched.  Not that I suppose it matters that much, but I had hoped to make whatever content I post here original material and not cross-posted, so it will make a difference in terms of what (at least) I do.

This essay will be deleted after I get an answer, unless others want it kept up for some time.
