A press release would be a good way to get this across to a different audience -- advertisers and competitors, mostly. (Actually, the company I'm with does some PR work; email address is in the profile). Just imagine reading a post like this from, say, the reddit guys. They might say "In the coming days, you'll see fewer Lolcats and conspiracy theories, and more thoughtful essays and insightful humor." But there isn't a clear path from here to there, and once we're there, we'll know about it -- so you're announcing something that either a) will happen, and won't need to be announced, or b) won't happen, making the announcement dishonest.
