Don't forget that those of us that still hang out here can evangelize too. (For instance the Lifehacker comment two of us made last week.) Make nice comments about Zenphoto on other people's sites, etc....
It'd be even better to actually have a article on a big profile site like Lifehacker, but they just did one on Gallery 2.
Since I'm also working on promoting my wife's website for her business, I'm doing a lot of "hunting" these days, and if I dig something up that might be a good promotional "vehicle", i'll post it here.
