One thing interesting about the state of web is exactly what you mention: "ship first, fix later."
With a recent project I made, I thought "I could really use a tool that did ____."
A few hours later, I made it, posted on Reddit, and a few hours after that I already had a huge amount of supporters and a list of revisions/improvements.
In the world of web, things move so quickly that it makes other systems look like a bunch of snails, leading to a quote I recently saw.. something along the lines of "What would you do if you weren't afraid?" Just release it!
Good topics can come of this and I look forward to listening! :-)
