  • Hey @thunderbird community, do you use Cardbook? If you do, I have a problem/question: I used to drag and drop Cardbook groups into the To:/CC:/BCC: field, but this doesn’t work anymore. Do you have an idea why? I use #Thunderbird 128.6.0es

#cardbook across platforms

every network with a public tag surface

Follow #cardbook straight to each platform’s own tag page. Where a platform publishes open data we measure it above; the rest lock their numbers behind paid APIs, so we link rather than guess.

X (Twitter) ↗Instagram ↗TikTok ↗Facebook ↗LinkedIn ↗YouTube ↗Threads ↗Bluesky ↗Mastodon ↗Reddit ↗Pinterest ↗Tumblr ↗

Every number above is measured from a named public API at the shown fetch time. Nothing is estimated or extrapolated. Platforms that lock their data behind paid APIs are not shown. Agents: the same numbers, as JSON, at /api/hashtags/cardbook
