Social media isn't meant for marketing, it's meant for PR. 37Signals doesn't use their blog for marketing they use it for PR and education. This attracts an audience, and once in a while they'll visit SVN on a day they're talking about Highrise and once in a while they'll go see what 37Signals actually does. Even when they launch software like the iPad app it's put in a PR context (we can make a paint prog with ONE color and get lots of sales, you can too!) If you want to post press releases on your Twitter you will fail, if you want to call out Salesforce as a silly business because of their margins then you will get readers in droves. If you want to use social media for marketing, buy some ads.
