There is a thing called Reputation (IIRC) tucked away in your profile. Im not sure if that's a true karma equivalent. Also not sure what you can do with it.
Ah, I love Preston Sturges. I guess I'm lucky to know a few film and TV nerds in real life. ETA: The Lady Eve is one of my favorite movies. (When I'm asked what my favorite movies are, I say that and I Know Where I'm Going by Powell and Pressburger.)
I deleted all of my comments using PDS. I just did a Google search for my username on Reddit and it had one result. I went to the post (I remember the OP) but my comment doesn't appear on the post. So is this a caching issue?
