If they're two rather varied thoughts in the same topic, just make a second post.
You already seem to be aware of editing past 1000 characters so you're leagues ahead of some.

I also agree that 'snip' is the worst thing. I don't know or remember what someone's replying to, especially if it's four pages back. Keeping context with quotes is the idea, and just replacing it with some word does nothing for me. I don't want to go back to the quoted post just to see what someone should have included in the first place.
