Dear 100 Hour Board,
Those of us who have been around for a while remember the days when you had to be logged in to use the Search function. Although I certainly don't want it to revert back to that, I am curious as to why that restriction was there in the first place. Does anyone remember?
I believe it was simply an attempt to encourage people to sign in so that reader activity could be more easily tracked (in terms of how-many-readers-are-active, not what-is-Pi-Hat-doing-today). Since we've been using Google Analytics we don't need to coerce our readers into signing in to learn about usage. Signing in now has real benefits though, like being able to mark favorite questions and add your approval to responses in the form of a "like." And, of course, you still must sign in to ask a question or submit a comment.
