I've decided to make that move, and this will take place later this month. Reasons I've landed on are:
1. Focus: I want to blog about more than Deep Church theological issues, including church planting, Christians and mental health, church leadership, teaching/preaching resources, the nature of full time church ministry etc. Running www.jasonclark.ws and www.deepchurch.org.uk is also a challenge in terms of focus and costs.
2. Deep Church - Jim Belcher: Jim tells me that my site was the inspiration for his book title :-) A great book, that has a strong presence under 'Deep Church', and I want to differentiate this site from there in terms of identity.
3. Future developments: A site under my name is easier to develop and change direction than one with a smaller focus.
The Deep Church site will stay alive, but stop being a blog and become a site for resources around that topic, and connections.
