The main thing to do after this is leverage this and get written up again and again.

You can google search for "How to contact a journalist/blogger." Basically, you want to appear everywhere within two months of the first major news story.

yeah, was already planning to pass along the mashable story to other industry specific writers and ask 'em "did you catch our mashable writeup?" and hopefully it could snowball from there.

i know when lifehacker picked us up out of the blue a year ago, a number of random smaller stories resulted from the domino effect.

i'm mainly concerned with how we can make sure the story is just spread across as many channels as possible as it's still fresh.

any message boards or communities that would help spread? (obv HN could be a great source...)

To keep something going you have to make it news again. In some ways this is easier, because it already was news and this is more of an update. In some ways its a lot harder because it is time sensitive.
