Myths was pretty good

One thing about first article though, nobody wants AltaVista crawler in their website. Most people I know blocks it in their robot.txt because they are very well known email address farmers and spammers. So I don't think anybody would care about Altavista abandoning some tags or such.
Actually both articles has some points. As far as I know, keywords meta tag is good for SEO. But if you stack up too many keywords, most of the search engines will consider it as spam and just ignore them.
Here are the myths I have heard:
- Do not use more than 10 keywords.
- If title includes some words from both keyword tag and the actual web page it is good for SEO.
- Keywords must be separated with commas. Otherwise search engines will see it as one long keyword and ignore it.
- If words in your description tag matches the keywords tag and the page content, then it is good for SEO.
Other than that? I really don't care. This is like global warming. Everybody making his/her own propaganda, but nobody can prove anything 100%.
I'd say go with what Google says:
"Do not build website for SEO, build it for your visitors and we will find you eventually".
