If you look at the last questions of this guy: http://stackoverflow.com/users/1906070/shiran?tab=questions you can see that they are about smalltalk/squeak and asked in last 2 days :).

In fact I think that we should support asking questions on SO, as a lot of people are anxious to register and talk to others on mailing list, and prefer to search for solutions on SO. If we���ll build reasonable amount of Q/A data, it can be easier for other people to start with Pharo.

Cheers!
