If you take a look on Google’s result page there is no keywords visible, but Title and Description only.
So use title with your keyword related to the page content to help search engines to find you. Use description for people to make them interested to visit your site. Use about 140-160 chars for description. Use 60 chars for the page title.
What happens if there is no Description on your page? Search engine will try to use your content or links names for the result page. Will it looks nice if you description on the Google looks like “Home – About us – Our products…” Put your marketing message for people in the description.
I would keep use keywords for other search engines if they will use them.
