I just finished setting up an LLC using Utah's One Stop Business Registration. This is an event-style eGovernment service that we first envisioned when I was CIO. It's been in operation for a while, but this was my first opportunity to use it. I was impressed. The application takes all of the various interactions you'd have with the State to create a business and streamlines it into one, easy to follow workflow.
The only criticism I had, and it's minor one, is that the application asked if I wanted to add any additional articles to the Articles of Incorporation, without giving me an opportunity to see what the application has placed there as part of the boilerplate. A lawyer would probably have a feel for that, but I didn't. I wanted to compare what it had put in with some of the Articles I have from other LLCs.
