Yep, I'd agree fully with going by your gut... if it looks right, there's probably a good reason that it IS right. I've tried applying the golden mean into my photos, but I admit my eye likely isn't good enough to see the pattern in everyday things. I do see the benefit in rule of thirds in some landscape photos and other situations, but if you stick to it as a rule, things will quickly get boring and predictable.
Also, thanks for the heads-up about the link!! Oops :\
