Off the top of my head, he's championed both the American Recovery and Reinvestment Act, aka the stimulus bill, and the recent health care reform. He's also nominated Sonia Sotomayor for Souter's replacement on the Supreme Court. I only get about as much news as you, so I can't think of anything else right off the bat.

Here's an easy list:

The big one will be health care, which is working its way through congress but would one way or another make health insurance available to everyone. Also, insurance companies would not be allowed to deny coverage based on pre-existing conditions, or terminate or cap coverage for sick people (a common practice currently). How exactly coverage would be extended to those with jobs that don't offer it or can't afford it, is still being debated.

Before that the economy/stimulus stuff dominated the agenda.

One of the first things he did is sign into law the Lilly Ledbetter Act, which promises equal pay for equal work among genders.  He closed down Guantanamo, released torture memos (in keeping with his promise for greater transparency), set up the new White House website that fosters participation in government by the populace (a mutation of his campaign arm), passed an expansion of SCHIP that Bush vetoed twice because "it covered too many kids," and he's working to pass reform on our nation's health care.  To that end, he has kept with his promise to give Congress some guidelines he's looking for and having them hammer out a bill all while being televised (something that he stressed on the campaign trail that was sorely lacking from Clinton's attempt at reform). 

One of my favorite things he has done so far (while of little significance to me personally) is opening up Cuban borders for people to visit and send money/aid to their families.  Having not been alive for the cold war, having closed Cuban borders has always seemed stupid to me.  I'm sure there's a reason, but I doubt it's a particularly good one.  So it was nice to see Obama taking steps to do away with that leftover bit of cold war retardedness.

I'd be more interested in seeing something from a remotely credible source.

What has Obama done as far as gay rights goes? All that I've heard is that he defended the Defense of Marriage Act and in the process apparently compared gay marriage to child marriage and incest. I'm pretty certain that everything I've read has been truthful, despite being from random but pro-gay sources. However, it still feels like I'm missing something obvious, when that is the ONLY mention of anything he's done with gay rights I can seem to find, good or bad. Is there anything else that's happened with gay rights so far, that maybe isn't as talked about, or that I've missed?

I was linked from the source from some other site, so it's not one I check frequently, or one that I know the credibility of. I should have linked this, my bad.

While I don't want to belittle the interests of the gay community, and in fact am a firm supporter of gay rights and gay marriage, I honestly think that right now Obama has bigger, more important issues to deal with. Sure, I'd like to see him do something to help the gay community, but congress is having a hard enough time just getting the healthcare reform bill through without getting interrupted by calls for apologies. Throw a debate about gay rights into the mix and the issues that concern most or all of us, like the economy, healthcare and the two wars we're in, could get even more bogged down.

I repeat, I do think gay rights is an important issue that needs to be addressed, but at the same time unemployment and underemployment are strangling this country. I'll be more willing to contribute time and effort to the plight of homosexuals after I and half of the adults I know can find a job, any job, and maybey not loose their homes.

Obama has implemented protectionism policies by imposing a 55% tariff on Chinese tire imports.

Can you explain this in further detail plase? I'm especially interested in the long term effects.
