  • I really should stay home and study this #sec503 material some more tomorrow instead of going down to San Antonio for BSides, but also I usually enjoy going to BSides... 😕

Follow #sec503 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.

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/sec503
