The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

An apologia for lazy evaluation
Did you use megaparsec between August 2018 and August 2022? If so, you had a space leak. Granted, maybe it was small enough that it wasn't "an issue", but it just goes to show that it's so easy to introduce space leaks in Haskell that experts do it regularly.

Functional Implementation of a parser?
The basic idea is to create a state monad (usually using the State monad transformer) which contains a string to be parsed, and which also lifts other monad transformers like Except for throwing syntax errors. Or you can use a parser combinator like Parser provided by a parsing library like Megaparsec or Attoparsec that defines an efficient State+Except monad transformer combination for you.

Splitting html tags string into list of string
The more "idiomatic" way would be to use a parser library, e.g. parsec, attoparsec, or megaparsec. But even then I think it would be a lot easier to maintain if you could preserve the angle brackets <> in the input.
