For me, I have found that a more concise language is easier to think in and write in. I recently worked on an application that was implemented both on the web using mostly javascript and as a desktop application in VB.Net.
One of the more complicated features I waited to implement in the web version, just because I found it rather difficult to think of the problem in VB. The javascript code was just easier to write and think in, and once implemented I could translate it to VB.
Although I do not know if there is a limit to the benefits of moving to a smaller language. Also, this is just my personal experience and I do not know how much it generalizes to other people.
