It's the end of another month, and time to update the tweeting clergy rankings for May 2011. The Bishop of Cork continues to sit atop the table, although the Bishop of Down is ascending the rankings steadily each month. There were a couple of high profile tweeters who are now ungraded, and have dropped out of the top twenty, enabling a few new faces to appear, such as Henry Hull and Simon Genoe. Personally, my ranking seems to be in a period of stasis, being joined by Harold Miller and Rob Jones on 78 while Victor Fitzpatrick motors away from me to 81. As ever, the rankings are provided by Twitter Grader analysing the Church of Ireland clergy Twitter list.
