As the OP I can see both sides. The threads that particulary interested me were the DIY Effects thread. It is so long and covers so mant types of effects and building methods that, in my opinion, it deserves a sub category in the same way the Lefties does in Bass Guitars.
The Interesting FRFR thread is the other one and I have stopped reading it. Again it meanders and often resembles a Helix supports thread.
Ironically I posted a piece of information in a long thread the other day and was castigated that i had already been mentiioned earlier in the thread. The very next post thanked me for posting the information. So I can see Ped's points and they are valid.
With the FRFR thread I have just stopped reading it although I see that it is a good resource for some. With the DIY Effects thread, I still think it deserves a sub-category.
