It was definitely colder this year, but not as rainy as last, and the parties were as off-the-hook as ever. One bad note: Facebook, your invite process sucked, and if it was 1/100th as hard to join your site as it was to get into your party, you’d only have 8,000 members today. The buzz around Facebook I heard at SXSW was almost uniformly downbeat: privacy issues, leadership issues, valuation issues, “spam” issues*. If it wasn’t already such a juggernaut, I’d be worried about it.
