feature creep is one of the major causes which kill startups
let me give you an example by reference to baking a cake, so you can avoid this problem
when making a startup (i.e. baking a cake), novice entrepreneurs start without a proven recipe or a list of requirements from customers (i.e. this is what I want in my cake etc..).
the result is, they mix and match all sort of ingredients to make one inedible mess, then no one buys the cake, the founder gets upset and figures the solution to the problem is to add more ingredients to the cake (to make it "better")
thats' what you're doing now. your product is not selling, you are getting annoyed, and you think the solution is to make a "better product".
that's feature creep. it's when entrepreneurs derail projects when they start adding new features to their product as a result of desperation. this happens because the founders don't know what they are doing (have no recipe) and/or have no idea what customers want (no list of requirements).
hot to avoid feature creep: never build products/services before you've sold them. that's how.
stop product development, focus on lead generation. think I'm wrong? try me. continue with product development and see what happens in six months.
