@miah @jwildeboer Sure, IRC runs on anything, but it still doesn't work for most people. I say this as somebody who's spent over a decade on IRC.
To get the very, very basic, not at all optional feature "message history", you need to run a bouncer. Which is a tall order for most people.
The amount of people on computers too slow for Matrix is much smaller than the amount of people who can't/won't run a bouncer.
@muvlon @jwildeboer As stated earlier. Message history is not a required feature. You simply never go into a social event and ask people for their discussion history for the evening.
I don't know why people using irc think this should be the norm. If you want message history, there are frequently logs for heavily used channels.
Let me ask this question, do you read _every_ line of text that was written while you were absent? And then I'd ask "Do you _need_ to read every line?"
