There's a new feature on E2. Now you can view the votes and reputation for any writeup you have voted on (as well as your own writeups) in a nice bar graph. The graph shows the monthly change in votes and rep since it was posted.
You can use this feature by visiting any writeup that you have voted on and clicking the "Rep Graph" link. The link will be right next to where the reputation is displayed on the writeup.
Please note that these are monthly graphs, so anything in New Writeups isn't going to be very interesting. Try looking at some of the older writeups you have voted on.
