Sam Ruby on "Share your OPML", after some subscribe/unsubscribe changes:

While the intentions behind this particular change are innocent, the fact remains that SYO in its current state is essentially un-auditable.

Dare Obasanjo objects the objection:

Doesn’t this apply to pretty much every online service? Or do you have the audit records for the Technorati Top 100, Feedster 500 or TechMeme’s current hot stories of the day?

Your comment seems pretty inflammatory given that this is the status quo in the online world today.

I think the difference is this: Technorati, Feedster (et. al.) are not playing at being our pal - they are businesses, and quite obviously so. Dave Winer likes to play at being "above the fray", which invites comments like Sam's.
