Subject is nice but there are too many advertisement.
This is disadvantage for the site, in my opinion.
yet once again, i must speak for adblock and noscript for fx. Don't see any adverts unless i turn it all off. I can't even get the pop-up ad to open to see how bad it is (well, unless i use IE... all those problems are solved )
As for the site itself, it might as well be a text document. There are no hyperlinks, downloads, only text with occasional bolding. With all the ads around, i wouldn't give this page a lot of credibility.
that being said, the content is good, and needed. Too many ppl shell out big bux for symatec when they can get the same thing for free. Continue to devlop it, and provide links to what you are talking about.
Oh yeah, and host the image you use yourself. The image is hotlinked from a different site. Move the image to your site. (And of course, do you have permission to use it.)
