I agree. Fraud isn't just endemic in Wall Street, it also exists in Software Engineering, and especially in "buzz" technologies. One of the dead give aways, is when someone says, "Trust me, I am smarter than you, and you just don't understand..", that is a huge red flag for any new technology. > > Jerry > > On Jan 31, 12:44 pm, Michael Bayer <[email protected]> wrote: >> I worked briefly with a project that used GWT (we of course ultimately >> rewrote the whole thing in pylons) for some portions of a web based >> administration tool.
