Sorry Sam but I can't agree with your method. But if it works for you and you are happy then by all means continue and enjoy the pleasures of your work.
No need to apologize, in the least. I have yet to meet another woodworker who does it the way I do it, so I must be doing something wrong.
Results are all the really matter, not how you get them.
I also don't think I look for a jointer to do what alot of folks seem to worry about, which is shoot for a finished quality side or edge right off the jointer. For me it is about establishing reference surfaces that lead to the board you are looking for ultimately, but can be handled better later on in the process by other machines. For instance, face jointing -- I don't try to achieve a perfectly flat board -- all I do is joint it enough to give me two rails (I always surface cup side down) two rails running the length of the board on either side (they don't have to be that wide, 1" is enough). I don't care how it looks coming off the jointer -- tearout, inconsistant mill pattern due to varied feed rate, a little bump or burn, etc. Once those rails are established they can ride on the planer table, the planer can take over, and do a far more consistant job than I'll ever hope to achieve hand feeding on the jointer. Same is true for edge jointing, though I seldom do this on the jointer with a slider handy, and in the days before the slider I had a jig exactly as Tod described. All my edges (and most final dimensioning) happen on the planer again, usually gang feeding up to six pieces at a time, as before giving me much more consistent results than tying to rip all those individual pieces just right, as each one is exactly the same width and saw marks are a non issue on the planer.
By just establishing a point of reference it also saves you alot of energy since you have far fewer passes necessary on a tool that can be labor intensive.
As for power feeders on a jointer -- they do make them, but they are specialty items. I have seen them with a pin wheel type of roller, the pins dig into the wood abit and pull the board along without much downward pressure, and I have seen a shark's tooth like roller that does the same basic thing. I know Comatic makes one, not sure who any other manufacturers might be. But again, these roller designs are to minimize downward pressure. If you let the board float, and just guide it, and your jointer is tuned, the machine will do its job without too much effort, really doesn't matter whether you focus on the infeed table or pay more attention to the outfeed table.
