According to my Twitter stats, the best carrier of my posts is AT&T in Dallas, Texas with Manhattan-based Verizon coming a close second. The best UK-based server is down in the fourth position behind Bell from Canada.
This comes as no surprise to me as about 80% of my e-book sales are in the USA, and I have a significant following of my posts in the United States. I never did sell much in the UK, one theory is the audience is more fantasy-based than science fiction.
I may try out the fantasy audience in the UK next year if I can motivate myself to finish my story - www.alsdominion.co.uk/the-reading-room/mordhiemicus.
