1) GUI
2) General media attention.
Done.
What's wrong with the web wallet GUI recently released?
And I would add #3: China. The Chinese largely drove 2013's runup at the end of the year and they are running up XRP/STR right now:

http://coinmarketcap.com/currencies/stellar/#markets
BTC38 is the #1 exchange for both of these coins. If we can get the Chinese community onboard then it'll be a huge win.
Nothing's wrong with the web wallet - it's fantastic.
Nonetheless, a local GUI wallet is fundamental to user expansion. I think everyone understands this so there's no need to expand upon it here.
Agreed on China, although it's difficult to determine the cultural weight of the libertarian argument over there. I suspect 'minimal government' and 'communism' are somewhat irreconcilable concepts. ;-)
