Awesome, I am both pleasantly surprised and shocked. The connection that JWs will latch onto mainly is that Rotherham elected to use the Divine name Yahweh in the Old Testament. I think they used to sell a non-WT printed Rotherham's at the back counter in the old days, before the donation arrangement. The copy I have is more recent and I do like the version, though the language is dated now and a bit hard to follow for contiguous reading.
I just looked at the WT online library and the Rotherham version they have there doesn't have either the Introductions or Appendices, which are really interesting and an education in themselves. Also, Rotherham's is the best I have seen for grouping the text so that the poetic passages are clearly identified, (indentations, etc) and the online copy is unfortunately missing these features. On the other hand, the online copy omits the various different fonts, italics and emphasis marks, which I always found more aggravating than helpful.
