Anchor text penalty doesn't work?!

[TheLastSeo]

How do you think, does the anchortext penalty exactly work? Keyword domains obviously can't over-optimize for their main keyword (for example notebook.com for the keyword notebook). And a lot of non-keyword-domains do optimize especially in the beginning for their main keyword to get a good ranking in google (and it always works). Is there any particular point (number of links) I can reach, optimizing for one keyword, after what i'm gonna get a penalty?

There is not like a set number for anything in SEO. But if you think its too much then it probably is. It depends on your competition and what they are already doing (google obviously likes what they are doing or they wouldn't rank).

mix them up, you dont want your anchor text to be all the same,
