Reading through a Hacker News all time hits list, I found a interesting question I'm also struggling with: how to get press for your application / website
Follow your competitors
1. Get a list of your competitors website. You probably already have one
2. Find sites linking to your competitor's website. It's that simple (a tool to do that Google "link:competitorsite.com" and Yahoo SiteExplorer).
Using Twitter
Follow people that are of interest to your product. DON'T DO THIS AUTOMATICALLY, you'll end up following tons of spam accounts.
Finding other blogs
Couple of places to get bloggers for your niche: http://technorati.com, http://alltop.com and social bookmarking sites, like https://delicious.com When contacting bloggers, people have successfully sent the bloggers snail mail instead to regular email.
