Sure, but look at the clusterfuck above where people are arguing about something called Quora -- they can't even agree on how you log into the site, because some people only saw it when you had to use Facebook.

Users will only give you one chance, if they see a reason not to come back then they won't come back, regardless of later changes you make.

I think you have the right goal, FWIW. For now. Because it's about priorities. Especially for a startup.

When you're building a startup, in my experience you want to advance on the narrowest front you can, as you build out the feature set and reach the market. Don't provide 5 ways to do X if you can just provide 4. Or just provide 1. Etc. There'll always be room in the future to iterate and add support for additional use cases, additional integration points, and additional polish. But you generally want to get to market fast, get real users, real customers, validate your market assumptions and business model assumptions, and slow or stop your burn rate before your runway runs out.

Saying NO to some things frees up additional time/money to say YES to others. So you should prioritize.
