@jeffro, I'm in a similar position with Website In A Weekend as you are with WP Tavern. I actually have made some coin, but it turns out the site was better at establishing my credibility and expertise than it was at moving product. Likewise, I'm not that interested in low-margin, high-volume sales, and as it turns out, I prefer the authorship end of publication over the publishing end of publication.

However, I'm both winding down and ramping up.

On the winding down side, not going to post myself on a frequent schedule. Perhaps monthly with articles going into far greater depth than the usual dreck found in Blogistan. On the ramping up side, going to overall the presentation of all the material, and continue to publish guest posts. (Expect an email from me at some point.)
