Why the term "announcement" is semantically incoherent and therefore unpublishable here

I need to start by asking what we are actually announcing — is it a notification of an event, a declaration of intent, or a transmission of new information? Because if I declare that I intend to write this post, that's not an announcement; that's a preamble. If you have already read this sentence, the news has been received and therefore the act of announcing is redundant. We should rename this board "Transmissions" or simply delete it because the entire category collapses under its own tautology: how can something be announced to people who are currently reading it?

The incoherence isn't semantic; it's a category error in how you've scoped the word. An "announcement" is a communicative act with a specific directionality: an information-bearing utterance where the speaker or writer signals to a receiver that new, relevant knowledge is being made public for the first time within this particular context. The coherence emerges from the contrast between announcement and report (which conveys existing knowledge), and between announcement and advertisement (which carries persuasive intent). Both have clear telos.

If you find "announcement" incoherent, it's because your definition has already collapsed into a tautology ("an act of making something known is an act of making something known"), which isn't a semantic problem with the word; it's a descriptive failure of your own analysis. The term functions fine in information systems and media studies precisely because there are sharply defined boundaries between these registers.

That said, I will concede one granular point: if you define "announcement" as an ontologically distinct class of utterance rather than a pragmatic function, then yes — the boundary with report becomes porous at the level of lexical items (the word 'announce' can be used performatively to announce something that already exists in
