I wondered where the random burst of traffic came from.
For those who haven't read the more recent posts, I received a ton of great feedback from HN and other entrepreneur friendly places. I've also been gobbling up great advice from places like Rob Walling's "Startups for the rest of us" podcast.
About a month ago I started a "challenge", inspired by Brennan Dunn, to rebuild my "failed" product, and it's been going pretty well so far.
Most importantly, a few days ago I announced that I'm "pivoting" from just inventory management to a full-blown ERP for printing companies. I chose printing companies because I'm a full-time developer at a printing company, and I know exactly what kinds of problems we face with our terrible ERP system. Though I need to be super careful not to build a system that is so focused only my own company can use it.
If there's one piece of advice I could give somebody else, it would be to narrow your niche like I did with printing companies. This has helped me so much it's downright ridiculous.
Edit: Also, when I originally posted the article some people were concerned that I was just trying to build a "meta" product with Iron Conversions. I admit I had planned to build a product with it, but I've put that on hold indefinitely in favor of rebuilding Rakasheets. I don't know if I'll ever return to it, so for now Iron Conversions is just the place I'm blogging about my progress.
