I have been guilty of this several times and will no doubt be guilty of it again. For all I know I'm guilty of it right now.
I saw this a lot with EJB. I was certainly guilty of it. Having achieved some success and decent understanding of EJB, I became an ardent defender of it even though it was terrible technology.
I see this same phenomena today with WS-*. I like to think that I learned to spot this trend with EJB and am wiser now, but for all I know I have Stockholm Syndrome with my messaging bias. I don't really think I do because I keep challenging myself to look past messaging in its current proprietary form.
I now think that I also had Stockholm Syndrome when I was an advocate of Rational ClearCase (sorry Sarge). Everyone new to ClearCase runs kicking and screaming from it because it is so complex. Once you suffer through the arduous learning curve, however, it is common to become a ClearCase zealot. I know, I was one for years! I'm dealing with this currently at work. Note to coworkers - I mean to offense by this and this is just my opinion. I think you are used to me by now.
Maybe I am just getting old and dumb and can only handle simple things.
