No, I don't expect to be served with any warrants or "National Security Letters" demanding that I refrain from mention of being so served. My impression is that those mostly go to organizations with large user populations and control of the databases of information regarding those users' doings, and KN@PPSTER is just a blog.

It works like this: On the first of each month, I'll update the Canary page to reflect that I have NOT been served with any kind of gag-order-accompanied government paperwork. If I don't update it (and/or if I don't say "oops, sorry, I forgot, I'll get that done right now" when some alert reader asks me why I haven't updated it), it means that I HAVE been so served.
