Iterate on feedback, absolutely, but don't iterate on feedback of hackers, iterate on feedback of people who actually want your software and are in your target market.
If you're dead-set on developers as your market, there are a ton of folks who still use svn with a gui because "no good git guis exist". These are the non-power-users of version control. You're not likely to find them here or on super-technical sites, but they do exist and there are many of them. The unfortunate part is that if you market to them you'll probably end up having to build an Eclipse plug-in.
