Ask HN: How do you advertise without spending money?
With a 2 man work force, I do basic advertising by sharing content of the product to free services (email, print stuff (brochures, posters, etc), twitter, facebook, flickr, youtube, this kind of services). I have also the benefit of being a designer myself, in this way I can deploy targeted websites, and somehow try to impress the potential customer with graphics or words.
(edit: It gets tricky to track all this services, though, without paying services who offer dedicated stats/tracking)
As a developer, what do you do to advertise without spending money (ie. by not paying services)?
Or, if you're a designer, what other methods do you use?
