I don't really like this thread...
But I'll tell my opinion on this.
I started as most of us, as a big noob in LP world.
LPA forums was the first place where I got so much support and new information, that I can't deny it's being one of the most greatest place for fans to talk about LP. It's a community of LP experts.
Though, after becoming LPL staff member I visited LPA quite rarely, due to me knowing a lot of info on my own already, and LPL having a lot of news on its own.
But still I do respect LPA a lot. And also we can't deny that it also was quite connected with the band, and had exclusive interviews, or releases sometimes.
But of course for me LPL is #1 LP related website nowadays.
I'd really like to see a better collaboration between these two sites, but I guess that's not gonna happen soon due to some disagreements between their admins, who, I hope, would make peace with each other.
