Of course. I wasn't replying to any particular post so just replied to the
subject. If a newsreader can't cope with that it's badly designed.

There's no such concept in the news protocol (you reply to articles,
not subjects or threads), so it's a bit naughty of your client to
allow you to do this.

That means different readers are likely do handle it differently,
and not necessarily how you intended. In a threaded newsreader,
it's a broken thread, or another thread which happens to have the
same Subject: but might not be displayed with the original thread
depending how it orders different threads.
