I never tweeted, I don't nosebook, I geeplussed for a couple of days. I've heard of photogram, snorpchat, and veins, but couldn't tell you much more than "they exist".
I have now concluded that was all cognitive self-defense as I fear I will dream a federated timeline tonight. I should have listened to @cassolotl while I still had free will.
I am reminded of the birth of the MUD concept when everybody thought it would be nifty to set up their own server. If memory serves, the rush settled down to a smallish set of devoted operators in short order to the benefit of all.
I never really MUDed, just thought the trend interesting. The desire I had yesterday to fire up my own instance which vanished by the time I woke prompted me to think on this.
