Been going for about three years now on the side, learned to code in Rails from Michael Hartl's book, got help from friends and have been getting tons of feedback. I find using Uservoice's idea generation tool was the best along with emailing all customers a few days after they register to get feedback.
I also found that a good amount of people will sign up and abandon the site quickly and I'm going to put in a JQ tour to help guide people around the app. Also been testing out Olark to gauge converting users.
Anywho, I just launched the latest, responsive Printavo update with has a ton of cool things screen printers need and use on a daily basis.
Any tips on converting more users are more than appreciated.
