it makes me a little uncomfortable that everything I write here is set in stone after 30 minutes.
The simple solution is to write your post with that in mind.
One thing you can do is make sure you post under "members only" if you are sharing something that you don't want to show up via search engines to non-members. Apart from that, if you are protective of your identity and you have something to say that can pin you down, it's best not to say it.
