For example, in one of the articles about this I found: "Most executives said that Hotmail, Yahoo! or AOL email addresses would prevent them from hiring prospective employees..."
That's why I created a BestHi.re: http://besthi.re - a service which will provide to job seekers a good looking and professional email address.
For now only email address is offered, but I have in plan to offer and blogs as well, like something what could help to job seekers without their own domain/blog.
Example: john.doe@besthi.re as email and john.besthi.re as blog address.
What do you think about the idea itself?
