760 million total worldwide internet users in 2003, vs 4.7 billion today.
Based on these sources, then, 1.3% of all internet users were using XMPP in 2003, and 0.26% of all internet users in the fediverse in 2023. As a proportion of all users, that makes XMPP roughly 5x more popular back then than ActivityPub is now.
XMPP had nearly 10 million users in 2003: https://web.archive.org/web/20071103080257/http://www.xmpp.org/xsf/press/2003-09-22.shtml)) Activitypub has about 12 million users now: https://fediverse.observer/stats
Thanks.
So not too dissimilar in terms of total numbers of users… however considering the growth of the whole internet’s user base…
