Concerning how to get GAF working on non-mobile, you have to clear your cache and then go to NeoGAF with an HTTP address instead of HTTPS.
As for Hunter X Hunter, it's definitely far more compressed than the original (for the first arc), but a better comparison would be to Fullmetal Alchemist: Brotherhood. There are aspects of the beginning that are better handled by the original. particularly due to the more relaxed pace, but the new anime actually covers later events that the original couldn't.
As for PPG, the reactions to the memes appear to be covering up the actual issues with the show that wouldn't be so easily fixed by future episodes, such as the action and general animation having nowhere near the energy of the original--partially because it decided to go with smoother animation instead of the quick cuts with dynamic poses of the original.
