I guess when a reliable WordPress plugin has an epic “oops” moment and crashes, but the author sends out a fix the next day, then that is something that should be taken in stride and accepted. I shouldn’t go shopping for a new “subscribers” plugin, because the old one is working. That one glitch should not be grounds for removal.
Still–I’ll never have the same warm feeling of trust towards that particular item. Of course, the whole idea of feeling bad because something that was free of charge suddenly didn’t work is a bit insane. After all–it was free.
