I think it is part of a general reduction in Mudcat usage. As I write this, there are 23 threads above the line and 13 below. A couple of years back, these numbers would both be more like 50-70. The Facebook Mudcat page no doubt has taken some of the activity away. Our average age may be getting higher too and our membership numbers are probably reducing (just a guess, I have nothing to support this). I still dip in a few times every week, but certainly less frequently than I used to. It may be that technology has moved on. This does not mean that this system is facing imminent demise, but it may become more specialist/scholarly in nature/content.
