I'd seen this so-called "Responsive" theme coming up in search results and being talked about on WP blogs for some time. I'd even visited the WP theme page some months back, and looked at the simple preview - but it looked bland & boring & didn't interest me.
So after working on several different sites with various other themes, I finally decided to see what all the fuss was about with this theme ... WOW ! The first thing to hit you are the superb ratings & reviews, followed by the most actively supported support forums that I've seen for a free theme - amazing !
So now I need to re-word my original thoughts - "bland" = blank canvas for you to customise how you wish, and "boring" = solid responsive framework on which to build your professional-looking site.
The search is over ... I've found my new home ...
