I have a bottle of Photo-Flo which is about 2/3 full and expired 10/2008. Should I just throw it away? Should I just use distilled water for the final wash and just forget about a wetting agent all together? Any and all opinions welcome.

Unless it's glowing in the dark, give it a try. It reduces water's adhesion to the film, which means the water tends to flow off rather than form the drops that cause spots when they dry.
I know some people don't use it, But, when I forget it, the spots are obvious.

it's just purified detergent. unless it got contaminated, shouldn't it last forever?

Also using early 1970s / late 1960s photoflow without a problem. I didn't know that it expired.

Sell it on E-Bay as "vintage" and buy a fresh bottle with the proceeds...lol
It should be fine. Good luck.

Concentrate will last forever plus some - I take five to ten years to use up a litre bottle, and the last of it is no worse.
Dilute Photo-Flo is best used one shot, or reused only for a day or two, as gelatin traces dissolved from previous film rolls may turn it into a breeding ground for germs attacking gelatin - which you do not want on your negs.

I've got one of these too, only I'm going on 23 years married, and I use it for every film I develop. I don't think many products had expiration dates back then... Maybe I will put it up for sale as "vintage", you never know

I once saw a guy from a chemical company being interviewed on TV who wanted to demonstrate the safety of Malthion, a rather serious insecticide, I think. He drank a bunch of it and lived to finish the interview. That falls into the category of "don't try this at home kids." Past due Photoflo, no big deal; just don't drink it. And, at 1:200 dilution, how much harm could it cause your film?
