Four years ago, I took this photo at a TechNet event in DC....

Yep, that lonely, staffer-free figure to the left was then-Senator Obama giving his vision on innovation and education just months after he was first elected to Congress.
I'll let Frank Davies of the Mercury News take it from here:
More than 100 tech heavyweights from Silicon Valley and elsewhere trekked to Congress and the White House during a one-day lobbying blitz Wednesday, celebrating recent victories and excited that the Obama administration is on their wavelength.
The executives from TechNet, a bipartisan network of CEOs, made a pitch to government officials that innovative tech companies can play a leading role in an economic recovery and help transform energy, health care and education — major themes of President Barack Obama.
"It was wonderful to hear the administration supporting much of the tech agenda," said Chris Kelly, chief privacy officer at Facebook. "They're also looking to use online channels to build on what they're trying to do."
Looking back:
Much of the day was spent with tech leaders thanking members of the new administration for supporting parts of their agenda. Several members of TechNet recalled that four years ago, a little-known senator — Obama had just been won election in Illinois — spoke to the group about tech issues.
"None of us expect or want the government to lead the next technological revolution, but I believe that we can provide the spark that fuels America's innovation and competitiveness in the global economy," Obama told TechNet in 2005. He decried cuts in science funding and the lagging deployment of broadband.
And, while the expectations were almost equally high when TechNet first trekked back for their first meeting with the Bush White House as a group (a meeting that was delayed -- it was scheduled for September 12, 2001), the observation was made yesterday that it sure is nice that technology and science now hold a high level of respect in the White House. Many heads nodded knowingly.
