Blogdigger blog: Indexing and privacy

Okay, so I’m reading the blog I just told you about, and Greg’s got a post about RSS indexing, searchability and privacy. Basically, his point is that while Email to RSS services are cool, they don’t neccessarily have privacy controls (yet), so when a person’s mail is indexed as an RSS feed, it also goes into the pool of data that can be search–ergo, your private mail can end up viewable in someone else’s query, or, as Greg says, “The result: what you thought were private emails consumed by your personal RSS news aggregator are really viewable by others.”
I’ve been talking with Mary Hodder and others about privacy policies and controls for blogging, RSS, and social network sites, and this is clearly a huge area waiting to be developed.
