In the last fifteen years of following I.T. analysts, I am unable to remember when one analyst group called another "dead on arrival", but that is exactly what ZapThink has done.
Going far beyond their bounds of providing useful, unbiased information, ZapThink took direct aim at Gartner and called their web services framework "Inaccurate", "incomplete", "unhelpful" and an example of "a horseless carriage".
In my opinion, the decision for ZapThink to take public aim at an older Gartner report lacks professionalism and maturity. Perhaps it is time for ZapThink to reconsider their own reports, to concentrate on their customers and avoid the below-the-belt attacks on the competition.
