I'd like there to be a separate Anonymous account for posting potentially controversial posts open for all.
Problem might be that it would be used to post frivolous off-topic posts, but reddit-like votes should keep them away from most users anyway.
Advantage would that you could also see what other people have posted as Anonymous nicely collected under single account.
Of course, if you want to post something controversial, you can always just register a separate account for that purpose. It's a bit more of a hassle than having a dedicated 'anonymous' account, but accomplishes the same purpose. (And if it turns out your controversial post became really popular, you having control of the account means you can verifiably reveal your identity, which you couldn't do if you'd posted it via an anonymous account.)
