I mostly answer questions regarding a specific tool on SO. I also provide professional services around this tool. I would like to use my answers in my own promotion material, primarily by linking to them from my own site. I am not talking about referencing my site from my SO posts, it's the other way around.
None of my answers contain anything along the lines of "contact me for further information and a quote" and I have no intention of using SO to promote my services. I want potential clients who visit my site to be able to see a sample of my SO responses as a barometer of my skills.
Is this considered inappropriate use of SO?
