I don't know about KaZaA but I remember it was very popular for a time, so it might have done some things right? What was its fate? Was it censored to death?

And I disagree very much that IRC is "semi-decentralized". IRC is completely centralized, it is just chat rooms on a server. You have to register on each server and each server has full control over its rooms and users.

I'm sure all the script kiddies who loved to take over channels in netsplits are gonna be disappointed that they never actually did that now.

More seriously, this is the second time I've seen someone on here characterize IRC in this (very wrong) way in the last day. Where is this coming from?

IRC networks are made up of servers that relay (hence Internet Relay Chat) with each other. You connect to one server and you can communicate both with people local to that server and people on other servers that are part of the same network (including ones that server is not directly connected to). Channels prefixed with # are shared across all servers in the network, while channels starting with & are local to that server (though rarely used).

I think you may be confused because you decided to rely on this loose concept of "semi-decentralization". IRC providers may use multiple servers, but that doesn't mean decentralization. They are closed networks, not very different from any sufficiently big internet business that runs multiple servers behind a load-balancer.

Part of it is that for users IRC definitely presents as centralised. You don't usually connect to a specific server, but rather a network that did some load balancing in the background. Like you typically connect to irc.efnet.org and not one of the sixty servers specifically.

KaZaA was also a big spyware.
