If I send a hashtag to a friend in Kik that says let’s chat about tonight’s knicks game at #knickskik, then that becomes a private group between me and that friend (and any others who we invite). I’ve done that so the #knickskik hashtag is now private on Kik.
But hashtags can also be public. If you have the latest version of Kik on your phone (came out yesterday), type #avckikgroup into a chat and then click on that link. Up to 50 of us can be in that group.
The cool thing about Kik is that it doesn’t use phone numbers like other messengers. It uses usernames and is not tied to your phone number or Facebook username. And so Kik, unlike other messengers, is used for both chatting with people you know (like other messengers) and people you don’t know.
That makes Kik an ideal platform for these public (and searchable) group chats. You can meet people in these public chatrooms and then take your conversations private in a one to one chat in Kik.
Ted Livingston, Kik’s founder and CEO, called this “hashtags as social networks” in a blog post yesterday. I agree with Ted that Facebook’s model of the one network to rule them all has not really worked and that many of us are using messengers as defacto social networks. My friend Kirk told me that his wife’s family uses a group in WhatsApp like their personal family facebook feed. I think that’s the phase of social networking we are now into and so Kik’s hashtag as social network model makes a ton of sense to me.
