I accept that you enjoy using Pharo. What is the output of that time enjoyably spent? What product does Pharo have the largest relative advantage in creating?
So is is good for doing some web application dealing with lots of devices.
Have a Jira client for doing lots of Jira automation using the REST API, along with a bunch of goodies etc. Pharo was quite practical to deal with that.
Am finishing up an XMPP client, and writing callbacks for dealing with XEPs etc is a dream in a live environment like Pharo. Expect more there soon.
Compared to other things I did with say Java or .NET, they all take longer and are more convoluted. I used to be a Java full time dev/tech lead/architect for years.
I am still doing Hadoop stuff but it all feels like there is always an annoying ton of accidental complexity in the Java/.Net camp.
Check http://pharo.org/success/Quuve for a rationale about picking Pharo instead of Python.
