The IM format is meant to be more conversational. Do you tag and categorize the conversations you have with people IRL? Probably (and hopefully) not. That’s the sort of comms that IM is meant for.
Both have their place, IMO. And it’s not like if you can only choose one or the other, anyway.
tag and categorize
that’s a whole other angle; one which i avoided altogether.
but i do converse in different contexts on different topics. i do like to recall things in an easier manner. i do like to do all the other things i listed in my OC.
im may have started as a conversational tool, but it’s pervaded every aspect of our lives now to such an extent that “whatsapp me” has become a generecised verb. in that process, as society, we’ve forgotten the benefits of email.
