What's the rule for using “who” or “whom”?
I was writing a LinkedIn recommendation one day, and ended up pondering for a while which of these forms to use:
… is a great developer whom I always found easy to work with.
… is a great developer who I always found easy to work with.
Both are basically correct in contemporary English, right? But is one or the other preferable, and if so, why?
(In this case I went with the latter, as it seemed more common (Google) and I wanted to avoid sounding unnecessarily “archaic”, although I’m not sure whether that would have been the case. Also note that I try to write in a “friendly professional” style instead of overly formal one. :-)
