well done...here are my thoughts: link to the twitter url, as well as any others that exist. also somehow work an #opendata hashtag in there to let people know of its existence, as well as encourage them to use it.
maybe post friendly links, similar to reddit; offhand, data science so and gis so are probably the most aligned, though heavier users would know better.
i would like to see something in regards to a collection of sets that come through here; my first thought is just to host them on github and keep a repo running, but i'm not familiar with so's internals, so i'm blind when it comes to knowing what we can and can't do. or should/shouldn't do.
having a repo of all the sets would not only alert more people of our existence, but also send some traffic i'm sure.
that's all atm...i know i have more, but i'm spacing out.
i do think we should do something for open data day....
