Exactly. Part of the reason they haven't been updated is due to
(a) the author's personal life having been a living nightmare that i wouldn't wish on my worst enemies in the time since and more importantly
(b) other resources having since become available such as Muppet Wiki. I'm flattered that there are still people who enjoy the guides and would like to see them continued...but given the reallife stuff i've had to contend with since, i'd need to see a pretty overwhelming demand for them to divert the appropriate amount of time and energy on them. Because a lot of the factual information is easily obtained elsewhere, i tend to think much of the value in them and what sets them apart is the commentary and humor i put into them and i'd be happy to resume work on them if a lot of people are really getting that much out of them. But here's a hint: that won't happen in 2012.
