When I first saw squeak 2 years ago, I just gave up immediatly and 
started with vw... Then I decided to use seaside and the vw port was 
just starting so I choose to use squeak and I don't regret it now that 
I'm used to it...  and for me 3.9 is more appealing than the previous 
version which is cool (Thanks all)!

I don't think mainstream anymore  ;)

Actually, I find it's even a bit more (than just web site application), 
a kind of showcase of the power of the whole stuff :)
... it's an entry points to squeak and also a real alternative GUI 
(multiplatform etc...).

Indeed, I think it would be really cool to have a web2.0 IDE (just for 
outsider to start to familiarize)... a bit like here:
http://mmm.seasidehosting.st/seaside/liveWeb  (not working now...)  with 
a cool live browser (like the class browser of scriptaculous). I'm sure 
such an app would call people's attention to squeak ! And once you're 
in, you're addicted :)
