So back to practical advice: what do you do if you’re a startup looking for help in getting the word out about your company? First off, don’t hire PR help until the volume of inbound requests by press are simply too much to handle without help. That’s way down the line for most companies.
Until then, take the time to start reading blogs and other publications that cover what you’re doing. Go to an event or two. This should be fun for you, since they’re writing about stuff that you’re spending all your time on. You’ll start to see links to other relevant sites, and before long you’ll fully understand who’s who in the space, get a feel for people’s personalities and passions, etc. Leave a few thoughtful comments. Better yet, start your own blog and link appropriately. And in your leisure time participate in the fascinating conversations occurring on Twitter and FriendFeed.
Suddenly you are no longer just a spectator with an agenda. You are now part of a community. You are a person that gives and takes. Someone who makes the overall network stronger. And I guarantee that after a few weeks of actually participating in the community, you’ll have far better press connections than most of the PR people we deal with daily.

There's some solid comments on the post contesting the assertions made. Here at dropcard we've witnessed blog pickup, but I'm pretty certain we'd hardly have the know-how to get into trade journals and the non-web-2.0 crowd. Could be wrong.
