I only came across this word when I came on this site and I at first, like mrs trellis thought it was a bit ugly sounding, with me also thinking it was pronounced like 'behind'
The reason I adopted it was that I have to write it out a lot in emails when sorting out the Joint Effort and writing 'anagrind' instead of 'anagram indicator' saves me 9 key strokes.
And that is about the only reason really.
