Chatbots on irc and things like reddit (e.g. mirroring images or quoting a bible verse from the name, or getting info about a user),or twitter (eg the wolfram tweet a program bot, or the deep forger bot) can be convenient for some things, but I'm not particularly motivated to make any purchases with one, or do anything with one that requires registering, or anything that makes me think it profits by collecting information about me.
