What are the general guidelines for using SE profile/s for the promotion of the freelancer and as the method for proving his skills?
I've heard that Java Black Belt account was a plus in some environment when applying for job. How it looks in the case of freelancer who wants to promote himself?
High reputation on SE sites is some measure of skills. In case of webmaster it would be reputation in SO, particularly in tags like JavaScript or CSS. In case of translator a reputation in ABC Language&Usage. In case of copywriter Writers.SE would be most adequate.
But how to point that I have high reputation on my web page/profile/visit card? Putting that information in central place is probably not the best idea, since many clients that don't know what SE is could be distracted. On the other side, placing the SE flair in the footer is a bit too little. It doesn't also point, in what tags I have gained the most reputations, that is, what are my key competences. And does SE belong in contractors CV or visit card?
