Discuss: namespace clashes expose and ensure instabilities in user-side solutions to interface problems.
Case in point -- the RemindMeBot, which will send a timed reminder message to anyone who calls it in a reddit comment with the phrase "RemindMe!", has been cloned and iterated upon by another bot, Kzreminderbot, which responds to the exact same trigger phrase. Both bots reply to the comment threads where they are summoned. Kzreminderbot has slightly more diverse features, including email/text notification, but the interesting thing here (I think) is the impotence of the response from the creator of RemindMeBot, who has added a link in their comment replies to send annoyed feedback to the second bot.
We talk occasionally about the scramble for usernames on new services, but this is an slightly novel example of the cascading hierarchies of website design. A feature which reddit lacked is added by a bot, but that bot is too provisional to cover the hole which it was meant to fill.
