simply put: mIRC scripting is not nearly as popular as it once was, and many of the older members who were responsible for the cohesion of this community have moved on and left. this subforum, for example, used to be teeming with off-topic banter, discussion about current affairs, etc. now it appears that we don't want to have anything to do with each other

nah, there are just other more fitting places to turn to for that sort of thing. just like the client itself: people used to use mIRC for a variety of things that it isn't really suitable for, but fun nonetheless. now this happens less and less, which isn't necessarily a bad thing ;P
