The GT people don't like boxing what it is into any specific category. Which isn't great for new users but also makes sense when you use it.

Because it's really not any one thing other than an environment that is built from the ground up for building highly explainable systems, including itself. Think about it like a "meta-tool", or a tool for building tools. Similar to how an operating system is a piece of software used for writing other pieces of software easier.

So naturally this type of workflow lends itself to data analysis. However it's no less applicable in building p2p networks, or working with codebases in other languages.

Regarding sharing code, it's actually really straight forward. Your classes aren't stuck in images, but are normally stored as normal plaintext files and committed into git. The library story is arguable better than in most other languages, because of how flexible smalltalk is.
