Keep in mind that she has won before, so it doesn't necessarily mean anything yet. It's a positive sign that the military junta even allowed elections (again) and that people were able to get out and vote but this is still going to be an uphill struggle to make it translate into actual reform. The Guardian:
Speaking to thousands of red-clad supporters outside the headquarters of her opposition party, the National League for Democracy' (NLD), the Nobel laureate called the election "a triumph of the people" and said: "We hope this will be the beginning of a new era."
Traffic slowed to a crawl as throngs of people, many of them waving flags and clutching red and white roses, spilled into the street to cheer, clap and call out "Amay Suu" (Mother Suu) as her motorcade arrived. At least one person was trampled underfoot when bodyguards pushed back the crowds and people swarmed to the car to see the woman who spent almost 22 years under house arrest and who many hope will create a new future for Burma's 60 million people.
Aung San Suu Kyi spoke briefly in both Burmese and English to loud applause and cheers from the crowd.
