What that doesnt make clear is that only one person at a time could log into a BBS so you often waited ages to get on... download all the messages and view them in a special reader.... make your answers.. dial in again and upload.... BBS would link to each other around the country and once a night would swap messages... so it could take 24 hrs for one message to be answered by someone accross country
As this was done while paying national rate per minute (and soemtimes the internet was when www started) thats why sig lines where kept to 4 and you had to post more than you quoted to stop over quoting.. also abbreviarions a plenty as every letter cost money
A lot of us brought the same mentality over to the WWW because we where paying per minute on slow modems and you didnt want to pay to download a 30 line sig on 100 messages say.... ALSO thats why SPAM is hated so much.. you where paying to download adverts
Now in the age of broadband these things dont matter... accept to old school who cant get it out of our system and stuck doing a lot the way we did
PS: Before BBS sytems (now we are going way back) we all used to write messages on floppy disks and pass round via jiffy bags and our loverly post office... to a network of users.. people could reply.. that could take weeks for a message to be replied to.. many many years ago I programmed a talking message creator so people could listen to text sent on a disk..... only for it to be reviewed in a computer mag as a tool for kids to swear and laugh....duh..
