Yeah and I must say it was one of the boldest decisions I took for CrazyEngineers. It also turned out to be the best decisions I took. I was absolutely in love with WordPress - but now looking back; I realise how much of my time was spent in stupid, unproductive things.
Disqus - I don't even want to hear that name again! It was discuss that caused our traffic to go down. Thankfully, we survived. WordPress may by an ideal choice for those who want to run blogs. But for those who're running xenForo; I'd recommend sticking with XF only and not use it in combination with other software or CMS. The add-ons released by talented people here will get you done 99% of the things.
With wordPress, we were creating content at two places and couldn't give our users a uniform look and feel all over the site. It turned out to be a bigger trouble than I initially thought.
I love xenPorta and keeping my fingers crossed that KAM will release an official CMS addon that can act as a front end for any community powered site.
