Either start putting together blog posts, so you can continue to pump out good content even after you get too busy to write it (technical, domain based, but "proper" article, not just puff pieces) , or adding features.<p>Although you should arguably wait on adding features until you get feedback.<p>I'm still at the 'building MVP' stage, but I have an Evernote file called "Awesome things to do to product when done" with links to ideas, products, blogs etc I see as I'm going along but don't have time to do now, or it's not appropriate to do now.<p>For instance, it was announced yesterday that Stripe is coming to the UK, so that blog post has gone into my list so that when I come to add payment, I don't have to think too hard about options. (Actually, thinking about it, you could certainly be coding the Stripe stuff now, even though you don't have the bank account in place... you know you're going to need it)
