There's a lot of useful discussion being made in the chat rooms - are they logged and saved for future reference? If they are, where can I access them - and are they indexable by Google?
If not, did the admins consider it? Why not?
I've spent some time in various chat room as of late, and I have yet to see any discussion that is truly worth saving. Most of it is simply noise and banter. And sure, while that might be fun (for some people) to participate in, it's hardly worth saving. No one is really going to back and read it all. The few bits that are helpful are likely to be extremely temporalized and/or localized. It's unlikely that anyone will go back and refer to the discussion for future reference.
If it's really something that's useful, you should consider promoting it to its rightful place on the site. Ask a question and then either answer it yourself or have whoever helped you in chat post an answer. Share the love (i.e., information)—that's really what a Q&A site is all about.
Actually, yes. Despite everything I said above, chat is actually archived and searchable. Each chat venue has a search page; for example, you can search the Meta chat rooms here. Moreover, the transcripts of public chats are indexed by the Google.
I don't really know why.* That's never been useful for me before, but they didn't ask me.
* But that might simply be because I'm a bitter fogey who just resents the fact that he can never fit an entire thought into the character limit that is so draconically imposed by the chat page's input box.
The logs are saved, if the room is worth saving

So, the room is frozen indefinitely.

I once had a discussion with a student regarding how to explain Quantum Mechanics to peers. I've had to explain QM to the layperson quite often, so this was pretty fun. Anyway, I found that the transcript was pretty useful later on--It served as a template for future explanations to others. Though this could be called "pretty localised" as well, since I'm the only one who will ever use it.
