2 Capital Letters: LinkedIn and email
2 Capital Letters develops ideas from real observations and explains their implications for agency work. Issues are read on LinkedIn. LinkedIn gets the thought; the email gets the artefact.
The separate weekly email covers one thing from inside a working agency’s AI setup: what was built, what broke or what held, with the file or decision behind it. It is written in German or English. The two lists are not the same publication, and the name 2 Capital Letters belongs only to the LinkedIn newsletter.
2 Capital Letters: Boundaries
- 2 Capital Letters is not a weekly email newsletter. Its former email identity is retired.
- The current LinkedIn cadence does not specify a fixed time of day.
- No subscriber count is claimed for 2 Capital Letters or for the weekly email.
