Posting old news

I've tried using search (both by keyword and by tag) but I couldn't find anything about this. What's Tildes opinion about posting old news that haven't been discussed yet? I'm not talking about your regular news post from a newspaper that is already too late to be discussed about, I'm talking about things such as software releases or old blog posts that have never been posted but would be interesting to discuss about. How would one tag them? Where should we post them if allowed?

Edit: I'm sorry but I won't be here for discussing this tomorrow or during the weekend. I'm not staying at home, but I hope I can come back to some good responses next week.
