To date I have declined the offer of advertising for this site. That might change in the future, but for now I prefer to not run advertising.
Simply stated; content is my priority. However, if some day I were to run advertising I would not go the common Google Ad-Words route. I would seek out a few select sponsors who would get premium placement throughout the site without degrading the editorial credibility or appearance of the site.
Based upon this if you feel that you have an offer that I simply cannot refuse feel free to let me know. My contact details are given elsewhere hereabouts.
I gratefully acknowledge several companies who sponsor the VoIP Users Conference. As acknowledgment of their support for that community organization I link to product pages on their sites where possible. Much of the proceeds from the VUC sponsors go into Kiva loans in third world countries.
