i ddos my wordpress-activitypub-enabled website every time i boost a post made from there to my 10k followers. tried every single caching plugin for it as well.

activitypub scaling is a very real issue

open social web is used here as a descriptive term, to mean the collection of networks that includes activitypub, atproto, nostr (and potentially more like matrix and farcaster, depending on your inclination).

whether open social web is the correct term or not does not really matter, because if it was not than i would simply have to replace it with another term that describes the exact same thing

i think the main takeaway is that the fediverse has hugely overindexed on relays being this big huge centralising force in the atproto network. And thats simply not true at all. The flipside of that is that relays also dont really matter much either. All they do is simply aggregating from a distributed network of data storage into a single firehose. Its really cool that you can do that for super cheap. but its also just a small part of the entire network architecture. like, atproto relays are not CDNs, for example, and video CDNs are expensive to run.

because hosting a full-network relay is super cheap, including bandwidth. there are multiple people who are running full-network relays (monitoring and relaying everything from every PDS) for less than 30USD per month
