One thing that makes me feel good is how united the online left appears to be about the importance of DADT repeal. It's not something which impacts most of us, and something which only directly impacts a small minority of an already fairly small minority, but the obvious injustice of DADT seems to resonate nonetheless.
When I started blogging I'd say people were less united on gay rights issues generally, that more people didn't see them as being particularly important, and were frightened that such things would repel voters who were afraid of the gay. There's much greater unanimity that equality is important.
