I’ve finally made a domain for this project: declutter69.com.
All the tutorials are going there.
I’ll leave the old product pages up here, and delete them as things are sold.
Traffic, or lack of it, was the main reason for leaving. I think I may have put too much information into this site, too quickly, without a lot of thought, with the effect that Google decided it wasn’t a quality site.
If you’re interested at all in the SEO aspects, there’s a post on the new site with some details.
