Agree completely with your evaluation of Twitter. I've used it for help with technical issues, feedback on articles, and establishing my personal brand. I also get satisfaction helping others with their issues in my areas of expertise. Paying it forward = happiness.

Since the Obama administration has a once in a lifetime opportunity to do something politically bold, how about increasing the tax on each gallon of gasoline? It could be structured so that it phases out as prices increase. Keeping gas at a more realistic (high) price will encourage Americans to drive less, take mass transit, and buy more fuel efficient cars. The will mean faster innovation of alternative energy and breaking our dependency on foreign oil.

The proceeds could be used to fund the infrastructure improvements and tax credits for the development of greener alternative energy.

Yes I agree by increasing taxes on those who earn above an arbitrary threshold (like $250,000) we penalize those who have worked hard for the American dream and found success. Won't that discourage our entrepreneurs from taking the risks necessary to hire more workers and invest in more equipment? We need a fair tax system that encourages small business to reignite America.
