Activity over time
Monthly volume with a 12-month average. Drag across the chart to filter every section below to that period.
Most active people
Messages sent in the selected period. Addresses sharing a display name are merged into one person.
Messages per person
How many people wrote how much. Open-source participation is lopsided by nature; this is the shape of it.
Contributor table
Click a column to sort. The spark column shows that person's messages per year across the whole archive. Domains, not addresses — see the privacy note below.
Who talks with whom
The 80 most active people, joined when they appear in the same thread. Node size is messages sent; line weight is threads shared.
What they talk about
Each thread is filed by keywords in its subject line — a plain rule list, not a model, and about a sixth of threads match nothing. Colour is that topic's share of the year's threads, so a quiet year still shows its mix.
Threads
The biggest threads by replies and by duration, rebuilt from message references and falling back to normalised subjects. Click a column to sort; titles link to the monthly archive.
When people write
Messages by weekday and hour, in each sender's own local time.
Sender domains
Share of messages per year by the domain people send from. Free mail providers dominate, so this says where mail comes from, not who pays for the work.
Newcomers and regulars
People posting for the first time each year, against those who also posted the year before.
