You're right.
And without a trace of butthurt, I offer the following. Please (!) if you'd rather not read the occasional off topic comment from me, do this:
At the extreme upper right hand corner of the page, next to "Sign Out", you'll see your login name.
Click on your login name, a dialog will pop up. Click on the "Manage Ignore Prefs" link. On that page, in the box below "Add a new user to my list", type "Jamie", and check the "Posts" option. Then press "Save Changes".
This simple action is all you need to do to never, ever see an off topic comment (from me, anyway). It's why its there and what it's for.
Guys, really. I will make the random funny (to me, anyway) comment. I totally understand if that's not something you'd like to read. You can ignore me and I won't care. It's not rude, it's not offensive, you won't hurt my feelings, it doesn't cost anything... everyone wins.
