Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I think you are right about STM being roughly equivalent to snapshot isolation.
What STM offers is an easy way to invent "containers for snapshotted values" aka TVars. Using them carefully may result in better scaling: https://hackage.haskell.org/package/stm-containers
What are some alternatives?
stm-incremental - A very simple interface for incremental computation using STM in Haskell.
restricted-workers - Interactive-diagrams
stm-chunked-queues - Thread communication queues that group items/requests that occur close together in time
theatre - Minimalistic actor library for Haskell
conceit - Concurrently + Either
named-lock - A named lock that is created on demand.
stm-hamt - STM-specialised Hash Array Mapped Trie
stm-channelize - Transactional I/O for duplex streams
stm-queue-extras - Extra utilities for STM queues
epass - Baisc, Erlang-like message passing for Haskell.
stm-conduit - STM-based channels for conduits.
pulse - Haskell: Synchronize multiple actions to be triggered as parallel as possible
