Yes, i appreciate that meta keywords are not what they once were...but still, every little helps and there are still *some* SE's using them out there!
I just find a bunch of one word keywords is less likely to be any good than phrases. I have seen your optimisation to avoid words of less than 3 letters, but i haven't yet found that to be a major problem in my case...(famous last words
I reckon even adding the whole title as a keyword phrase would be a step in a better direction...that should be an easy hack for me to do by myself...but turning a 3,4,5,6 or 7 word phrase into 3,4,5,6 or 7 variables in order to output the various sequences is beyond my simple understanding of php!
