Just because not everyone wants chords, or wants your version of the chords, or even wants accompaniment at all, is no reason to quit posting chords. Some people ~ in the future if not right away ~ will put them to use, even if they don't stop to express their appreciation.

Like Malcolm Douglas said very early in this thread, chords are not really helpful to someone who does not know the tune (with the exception of Uncle Dave-O, whose creative approach is pretty interesting) ~ and for many of us, if we know the tune we can usually come up with a basic three-chord arrangment.

But then again, as M.Ted pointed out, there are harmonically complex songs where the (non-standard) chord progresions would be very tricky to figure out and where a set of chords is much more helpful and more necessary than for the average folksong.

Speaking for myself, I don't "need" chords for all the songs whose complete lyrics I might need to look up. When I'm trying to come up with a way to play a given song, and can't come up with a satisfactory arrangement on my own, I'm more likely to search for tablature than for chords ~ either to follow exactly or to adapt. I hope I'm not opening a can of worms here ~ the mere mention of "tabs" seems to be a controversial topic, at least among some of us. I think we all agree, however, that much of the tablature found on the internet is of, shall we say, suspect quality.
