Great article Ben, and thanks for directing me toward Upscribe, missed that bad boy, but will be putting it to good use now.
Yeah, Sprint is a great guide and have put many of its points into practice (alongside the bible that is Hooked).
I’m pushing out a project soon kissmyUI (how punk!) http://kissmyui.com and from inception to its launch (which should be around 1 week or so), will be around 4 weeks. A little more than you mentioned in your article but I’ve had bills to pay ;)
