No, I don't think it's fair to say that. There is a mixture of issues 
involved: First, Tweak was never polished in any way and it should have 
been before a "wide release" but I never found the time which made it 
strictly harder than it necessarily had to be (to insert a pseudo 
Ballmer-quote here, imagine him shouting "tutorials, tutorials, 
tutorials, tutorials" ;-) Second, it was intended as a research project 
so I tried a number of ideas that I had been discussing with Alan for 
ages. And, as usual, some of them work, some of them don't (and the ones 
that don't leave an unpleasant smell). Third, I  just generally don't 
feel up to following through on the storm of emails that *any* proposal 
for changing the UI framework again would create (personally, I don't 
think anyone can really change such fundamental things in Squeak unless 
it's either strictly incremental or comes as a fork - and if it's the 
latter you're better off if you have a "movable" code base like Seaside 
and solve a problem that isn't solved in other dialects either, again 
like Seaside). And lastly, changing jobs and changing servers and now 
working at a startup which requires 120% of my time isn't exactly 
helpful either for finding time to spread the word ;-)

Indeed this is probably the best. Tweak is being used in Qwaq's products 
  btw, so if you go to www.qwaq.com and check out our new intro you'll 
see some Tweak in action.
