So you're a tech founder wondering what to do during marketing week for your startup. This is an article I wrote which details some of the marketing stuff I did over a year. Other than that, here are some ideas:

• Tweet something of interest to your target market
• Participate in forums where your customers are
• Improve your marketing site / docs
• Create a free tool that complements your app
• Write a blog post aimed at your target market
• Write a weekly / monthly newsletter with tips / advice
