Yes..... I sold out. There is now a google adwords space on the top right on the sidebar and at the bottom of individual posts. I went for what I think is the most unobtrusive design they offered.
Google have emailed me adwords related stuff for ages and I have resolutely resisted as this site is in no way a marketing site. However, in the last few months the site and related equipment failures (power supply, hard drive, mail server etc) have cost me quite a bit and hopefully this will help me recoup some of that.
Looking at what they seem to be placing as ads on the pages I have been starting to wonder how good their contextual advertising is... still it's early days.
In related site news the forums are now permanently removed, although there are still some links left over as I write this. With the amount of spam / hacking etc its just not worth maintaining a forum on a small site like this.
