Good question, xanderman!
I feel that a lot of ILP’s critics are people who have not yet seen how bad many of the other large philosophy forums (out on the net) really are.
This is mostly likely not the case in every situation, but I do think it happens a lot here.
I’ve made extended stays at several of the other large philosophy forums out there in the last four years. I honestly can tell you that none of them were half as conduscive(sp?) to philosophical conversation as ILP is.
Here’s why:
NOTE: I’m honestly NOT trying to critize these forums, or bring negative attention to them – really, I’m not. I’m only highlighting the Good and Bad things about them to give others here a taste for what they are like.
PhilosophyForums.com = Great site in general. It has a lot of members, which means a lot of good topics. But it is incredibly “political” among the members there. Not a great place to start if you are at all new-ish to philosophy.
SciForums.com = The perfect example of a forum that is not well-moderated. Sciforums claims to have an “open-government” (the members make many of the big decisions regarding how the forum is run), but the lack of moderation gets in the way of otherwise-valuable threads & topics.
Frostcloud.com = Good forum, but not real active. It has it’s following.
KillDevilHill = Not a bad place to talk philosophy, but it uses a rather odd Bulliten-Board System that is cumbersome and ackward to use.
So, in retrospect, ILP is actually doing pretty good. No one forum is perfect, but I feel that ILP has decent members, a well-qualified team of staff members, and a lot of interesting topics.
…Just my humble opinions, anyways (sorry this was so lengthy).
