Aaron Hsu's newsletter mixes detailed, hands-on tests of affordable pens (judged on glide, feedback and wetness) with in-depth explanations of array programming in APL. It also announces APL workshops and related events.

Personal reviews and commentary on carefully designed everyday objects, especially fountain pens, luggage, clothing and outdoor gear. Readers get detailed hands-on impressions covering materials, construction, fit and finish, and how products hold up in use.

A UK fountain pen blogger publishes detailed, opinionated reviews and reflections on pens, inks and stationery, such as a hands-on comparison of Sailor 1911 nibs and a candid yearly wrap-up of collecting habits. It suits readers who want informed, personal takes on specific pens rather than news or sales listings.

A personal blog-style newsletter featuring first-person recaps of the DC Pen Show alongside occasional reflective essays. Readers get an insider's view of the fountain pen show scene from someone who works a vendor table, plus personal life and career lessons.
