So everybody ignores Meta Tags right? Search engines know that poeple put any old junk keywords in them to attract traffic, so search engines completely ignore them.
Tagging on the other hand is flavour of the month. For some reason, blog search engines at least give significant weight to tags, and assume that people are not tag keyword stuffing.
I give it three months.
* Any resemblance between these tags and the post content or the top 5 current searches at technorati is purely coincidental.
