You know, that is the thing about considering bait as an attractant to bring in hogs you don't have. It probably doesn't work like people think it will work. If they don't already know about bait on your property, then the only reason why bait is going to work for hogs is because they don't have other reasonable food sources between your bait and where they are. If they do, then they won't make it to your bait. Certainly, that may be the case during very lean times, but there are probably already other hunters in the area feeding hogs as well.
Like you said, if the baiting worked as an attractant like people wanted, then you would be getting LOTS of critters from all over coming to eat your bait. You never hear of reports of a person putting out bait (corn, soured corn, hog wild, beer corn, jello corn, kool aid corn) and then all the hogs disappearing off the neighbor's property to come eat the new bait.
It is more likely that you have hogs (and deer, etc.) making passes through your property on an occasional basis if they aren't actually already there. During their normal activities, they may pass by your bait (in relatively close proximity) and only then discover it. Then they make use of it.
Where the baiting really comes in handy is that once discovered, it tends to bring hogs back repeatedly and helps hold them in place longer for shooting.
So do bait with whatever you want to use and set up a game camera to see what shows up. The nice thing about dry corn (plain or treated with powders like dry kool aid or jello) is that you can put it in a feeder and it will do its job for 1-2 months or so without you having to replenish it. That gives the hogs plenty of time to find it.
