Thanks for the website design suggestion. I took you up on it and increased the font size and line height to make it easier to read.

Mr. Free, its not any worse than using commenting for link building. You just have to be careful. If you make sure you submit to relevant directories in a way that would be useful for users, then you’re fine. Just like your comment – crafted with good enough English to almost pass for sloppy typos, somewhat on topic. If this blog wasn’t human moderated and I just let any comments through, I would get a penalty for linking out to anyone and so would your client who apparently sells voice over IP. The same would go for a directory – you would both get penalized for building links carelessly and for giving out links carelessly. You better be careful comment link building using your exact keyphrase for anchor text. People are saying Google is acting out against repetitive keyword anchor text links. You better be changing up the anchor text keywords you use for your commenter name as much as possible if you don’t want to get your client penalized.
