Steve.. I have seen many of the sites that show filming locations and synopses of plots and even interviews with various cast members. There is even one called "SummerWinos" that intended to be an analytic blog from two guys about every episode. I don't know if they ever finished it, but it stops at season 9.
   People used to comment on various aspects of the plot and characters. I have my opinions on the 'best' periods and characters, but never bother any longer with the last 3 seasons when they introduced "Hobbo" and the plots changed from silly to stupid.

I think I might have quit watching if the addition of Entwhistle hadn't perked it up.
