At Firebase we used an adoption funnel and activity map to plan event activities, mapping each action to a user stage - from Awareness to Love. It explained (to leadership) why we were at so many events (>150 per year at peak) and what success looked like.

Developer Relations events work often feels intuition-driven: we choose our talks, swag, community, content based on feeling and experience. But you can bring structure to it using the same tool marketers rely on: the adoption funnel.

Happy digs into how real-life struggles of the players shape their in-game choices. Great characters, smart pacing - though power levels climb fast. Still: excellent setup for when all storylines converge, which can't be far off.

This third separate storyline in the Awaken Online universe (after Jason’s and Fin’s arcs), follows Dom - a college athlete diagnosed with terminal cancer who’s offered access to Awaken Online as therapy.
The character work is rich here, both for Dom and others.

Pebble is back ⌚️
Almost a decade after Fitbit shut it down, Pebble relaunched its e-ink watches: sunlight-readable, week-long battery, and built for simplicity.
I got the Pebble 2 Duo and here’s what it’s like to use a smartwatch that still values time over touchscreens.
