Voted stay for now, out of loyalty, because this site has been a mainstay for so many years and they've resolved problems before, but if MAD continues to be difficult to access then there's likely to be tipping point.
The concern, as Wedgie_Pie points out, is that we could end up losing some posters altogether, and/or posters get split to a degree where neither site is well-enough populated to maintain the traditional energy.
