Remember the Tamagotchi?  Little plastic toys containing a virtual pet that you have to constantly feed and play with?  I never had one myself but I was amused by my son's short addiction over a Tamagotchi.

Reading Esther Dyson's Blogger's block reminded me of Tamagotchi.  In a sense, blogs are like Tamagotchis because you have to keep feeding it to keep it alive.
