This is still the first place I check when I fire up the interweb.....
The forums (especially this one) are still the place for knowledge/discussion on thier particluar subject. Many google searches on specific information (related to the Mk5 platform etc etc) still brings you back here due to that depth of knowledge.......you don't get that with Facebook.
Personnally I find the Mk5 Facebook groups can be very childish but that's to be expected as the cars are now cheap and kids can afford to buy them now. True, if you're after a quick answer and can't be arsed (or don't know how to navigate a forum's library) then you're at the right place.
Most importantly (or more importantly) this forum, in particular, is about the people as much as the information. Some great peeps on here that I just don't find on Faceache, snapcrap, instash*t or twatter.
Ohh and I'm old and I'm stuck in my ways....ill be here (still pontificating) when the forum closes the doors and turn off lights.
