I've had another thought re subscribing to blogs. This is really only relevant to anyone who is concerned about keeping their email address private.

I don't know if everyone is aware that the email addresses of people who have subscribed to their blog appear after they publish a post. (The screen that goes on about pinging people etc.)

Now this doesn't tell you who's email address is whose but if you have a fairly obvious email address eg my name@yahoo.com, then it will clearly be obvious whose email address that is.

Hopefully, most people won't be bothered about this but if anyone is they may want to get a new email address with a fairly obscure/vague address.
