Does anyone else use the visual feedback shown, after giving a tip, as a method to indicate what you've already read?

It actually works pretty well as a time-saver. If the row has the yellow lightning symbol, I can scan right past it. Just like the read/unread indicator in my e-mail client.

I used to do this "upvote/downvote to indicate what has been read" trick on Reddit too.

But it is nice to be able to glance at the front page, or recents, and know the quantity of posts I have not seen yet, and then easily go through them.
