Blog vs no blog
A six-week experiment, 19 October to 29 November 2026.
I launched two identical products on 19 October 2026, Gripelens and Quibblemap. Gripelens gets four blog posts a week. Quibblemap gets nothing. Everything else is the same. The rules, what I measure and what I expect are in the first post. This page lists everything in the series as it comes.
