This is LWN.
You don't need to explain that it is possible to communicate with other developers over mailing-lists and/or IRC.
You don't need to explain that many developers are geographically dispersed.
You don't need to explain the difference between real-time chat and email, nor why one migth want to use both types of communication.
You don't need to explain what "IRC" means or what an "IRC Network" is.
And you very very definitely do not need to point out that terminal-based programs will generally also work in an xterm (or equivalent)
However, when you remove this useless fluff, what's left of this "article" is: 'There exists a terminal-based IRC-client named Irssi, it can have several windows, and can be extended by scripts. One such scripts makes adjustments to topic-handling.'
Which is completely useless. Sorry, but it's the truth.
