I've set my Genesis/Lifestyle set-up live on my blog: kneel in wonder at heaven touching earth
I initially found Genesis to be quite a steep learning curve (perpendicular!), but have now managed to get things looking very similar to how I had them on 'classic'. In the process of that I feel I've learned quite a bit, though I still feel somewhat out of my depth. I think most of my customizations are relatively simple, but nevertheless, I am happy with the result.
I shall continue to tweak things here and there; and possibly even a redesign. But I have another project to get stuck into now, one that I've been putting off for too long.
