Notice the past tense. I based that opinion on the many aggressive attacking posts by Zed (for which he is well-known), particularly the attack of Mark Pilgrim (now deleted.)
That impression may be right or it may be wrong, but for good or for bad it's one that I got, and I felt my not mentioning that or hedging it here would be intellectually dishonest.
Note what I said next:-
"but this comment which is sincere, genuine and offered to someone for whom this could be greatly helpful has made me seriously reconsider. Kudos."
Which I really meant sincerely. It was actually meant to be a genuine compliment, but it is really hard to put that across without sounding sarcastic. Ah well.
