    No notice, no word, nothing. This is dumb. Fun game and now you ruin the whole site. You can keep it. I was set up to hit it big this year and now you took the game away. Well you can keep your site. I will not be back. RD

    SciTech Politics: The New Space Race

    By Posted on 10.29.2008 3 Comments

    Fifty years ago last month, NASA opened its doors. The launch of Sputnik the year before had rattled the United States’ faith in its technological superiority and pushed it to assert itself as the leader in space. In the decades since, that dominance has scarcely been challenged.

    You know all this money we are spending to bail out these people that signed contracts and now do not want to hold up their end. Forget them. Spend that 700B dollars on a trip to Mars, the moon, where ever. No it is not safe. Coming to America in 1492 was not safe. Some may die. Get over it. If we wait to cross all the t's and dot the i's we will never get anywhere. Seat belts, helmets, one third the cost of an auto is gov. compliance. Man is losing his ability to challenge the unknown, because someone says you cannot take that chance. Well it is my life to live or die the way I choose. If I choose to try for Mars and die. I went well. MAN up America, get a life. Yes I know I can't spell. Oh well.

    Dear Mr. President

    By Posted on 10.28.2008 5 Comments

    Good morning, Senator (or should I say "President-elect"?), and congratulations. You talked during your campaign about using the Internet to engage with regular folks, and surely you did. So did your opponent. The last time I checked, the two of you had amassed about two million friends between you on Facebook and MySpace, and another few hundred thousand followers on Twitter and YouTube.

    Seldom have I ever read anything less worthy of reading, so I quit after 1 of 2. Hide everything on line where the old folks that actually vote do not venture. Science is good and the internet is good, but sometimes old is better.
