Are you working on a desktop software?
hbien: I make an app for the Mac which is doing pretty decent.  Not enough to replace a full time job, but almost enough to cover rent.* For distribution, I just have a website.  I also put it up on the Apple downloads listing, which is where most of my traffic comes from.* A bunch of other sites pull data from Apple's listings, so I get traffic from there too.* More updates = more traffic = more sales, because each update gets you near the top of the download sites* Sales are done through PayPal, which is really easy to setup* Support email isn't bad at all, maybe 1 email every other day* The free trial limits the amount of data you can enter, rather than a time trial.  That way users can try out future updates too.* When a major site did a post about it, sales AND feature request emails spiked.  But after a week, it goes back to normal.
