I did not find anything against this in the guidelines, but if there is something wrong with the submission then apologies in advance. I believe that services companies and recruiters make a living of hiding this information from the developer community, and often take a 20-25% cut just for sending an email with a CV, a second email to schedule an interview and sending a contract for signature over the post. This is a proposal for replies:
Top level entry: "My current daily rate is RATE / hour or day, I work in COUNTRY"
Second line : "I work as a LANGUAGE Developer/Architect, I have X years of experience and my main skills are ..."
Extra details of whether is a remote position would be interesting as well. For replies to top level entries, comments of whether the person is being lowballed or not would help, even if you prefer not to give your rate yourself.
