Mail 3.0: Links in subject now clickable

So either no one has emailed me with a URL in the subject line since I’ve been a Mac user (a little over 3 years), or Leopards Mail 3.0 has a new “feature” (if you want to call it that).

Clickable Links in Subject

No, I don’t send emails to myself. :) Someone emailed me and in the subject they had a full link, which I then in turn noticed was now clickable when you view the message. It isn’t clickable in the listing of messages…just when you are actually viewing the email.

I haven’t fully made up my mind on if this is annoying or convenient. For some reason the first that that popped in to my head is how PR folks are going to start included URLs in the their subject to try to get you to click through to the site more…a negative thing.

Your thoughts? Or is this something that’s existed for a while and I’ve just apparently been oblivious to it all this time?
