How'd you market your product?

Hi, all!

I joined a few days ago looking for feedback. I love writing web applications, but have not a clue how best to market my products.

Do you personally rely on word-of-mouth, use Twitter, advertise...? What have you used?

I did have one idea that I thought was unique: create a splash/welcome page before the product is launched and offer it at a decent discount. With every sign up the price increases a few cents until it reaches the launch price. What do you think?
