4chan has over 1.5 Billion posts due to its /b/ board. However, people rarely venture into the other (albeit not as Work Safe) boards which can be informative if filtered correctly.
/g/ for example can be a great guide to computer hardware enthusiasts... however be warned, you have to really read through to sort out the idiotic postings.
Maybe it's just me, and I don't get it, but I simply cannot follow 4chan. It's layout just makes it impossible for me to follow.
