I belive SEO should be the same as alwais, and webmasters should not
worry about if the keyword is repeated, in capitals, with accent,
etc... I think SEOs should care to put in the meta keywords what users
usually writes in the search engines looking for what you are offering
in your site.
This way of acting brought me to have meta-keywords with arrount 2000
characters, and I just went back to the 800-900 characters, but just
because search engines are not doing things right, as I belive that if
I have 200 keywords related to my site, 200 diferent ways of calling
what I offer, it should be fine, and search engines shouldn't care
about spamming this way, spamm is something else, spamming is having 20
keywords that don't reflect the content of your site.
