Meta Description Tag - It's Important!

[espmartin]

The meta description tag can be viewed as your "first impression" to reach
your audience. If you don't use the meta desc. tag, then the search engines
will just scrape text from your page, and that includes the keyword that
was used by the user on the search engine.

Making a great first impression can mean the difference between a conversion
or not.

Agree about first impression statement and initial information about your site.
But this is as far as it goes regarding description meta tag from SEO point...
