As noted in Only Opinions, while the posts written on the blogs referenced by Resume Wiki are largely from Recruiting professionals, they are still blog posts.

As a result, they are subject to a certain disclaimer, which generally goes something like this (stolen from Jobs Blog):

These postings are provided "AS IS" with no warranties, and confers no rights. The content of this site consists of Recruiters’ and other employees' own personal opinions and do not officially represent our employer's view in anyway and is especially not intended to convey the views of any company or HR Department. Please visit the company's Careers Page for our official Careers information. In addition, the thoughts and opinions of participants often change, and as a weblog, this is intended to provide a semi-permanent point in time snapshot. You should not consider out of date posts to reflect participants’ current thoughts and opinions.
