At a crossroads-Whether to launch or seek more time/funding for more development

You will find that once you launch and start watching people and taking feedback that what ever you "think" is the right way won't be a vast amount will be driven by the users with your own vision as a guideline.

My advice is

• Release early. Get it to a good, basic set of core functionality that looks good and release it.
• Have the plan. Have a good queue of new things you want to have lined up ready for subsequent releases every few days or weeks. Keep this flexible and fluid IT WILL CHANGE.
• Enable early engagement. Make it easy for early adopters to engage with the site DON'T force them to sign up as the first thing, you will loose most of them.
  • You can store a GUID in a cookie and track their usage collecting details along the way until they are ready to give you more details.
  • When you ask for more details, do it in a minimal way ... too much too fast and you loose them becuase its either too hard or intrusive. Try using OpenID / Facebook logins makes it easy, people are getting used to them.
• Get feedback. Enable your users to give you feedback easily and watch what they are doing on the site. There are Saas offereings you can integrate which enable you to do this. (don't ask 1000 questions at once) 1 at a time, build up knowledge over time.
• React quickly. It is critical in the beginning to be able to react to the users suggestions and pain points.
• Build engagement. If someone sees their idea appear on a site they will have a higher level of engagement with the site. Possibly have a credits page to go along with it.
• Don't drive for money. If your model is focused on having lots of people don't make them start paying from day one have them ease into it with a freemium model OR percentage payment on the eCommerce transactions once they occur. See it as more of a by-product of a successful site rather than the focus of the site.
