Is any work being done towards the concept of trusting other people's S2 styles?
Consider: you've friended me and I happen to look at your friends page. On it I see my own entries, including private ones, but in your style. Unbeknownst to me your style "reports back" all my private entries to some server by loading images with my private data embedded in the URLs.
Now, I trust the official styles not to do this, of course. And I trust my own styles. But I don't trust other styles...
